Maybe it would fix your problem with heat when sheading old prints if you had two shredders. One that was course and a second one that was more fine, instead of trying to do it all at once?
Great video on showing how ideas come to life! I taught 3D modeling for over 20 years. The best advise I could give students about how to attack a design was to think of how you would make it using hand tools IRL. Like whittling a block of wood or machining metal into what you need. Or, how you would build up wood, or welding steel, to get to the final part. When I design for my shop, it usually uses both methods. Many parts just design themselves too. The other piece of feedback I have is terminology. You are not designing into your parts tolerances for the fit between parts. That is called a clearance, the space needed between parts in an assembly to be put together the way you want them to be. Very common accidental swap of terms. A tolerance would be how you could build a part dimensionally the wrong size and still work correctly. Like drilling with a sharp bit vs a dull or bent bit. You get a different sized hole, but they both work. The size difference between the hole sizes is the tolerance. (Tolerances are used in manufacturing so we can get more imperfectly mass produced parts that work with the required clearances in the assembly. I hope that all makes sense.) Keep up the great work and stay safe over there! Thank you!!
Really enjoyed this. As someone new to 3D printing and CAD I loved seeing you design solutions to your problems and how you use your software tools. I’d really like to see more of this kind of content. Thanks.
I like how you show your solution but also asks for help for problems that you haven’t solved! I’m starting to learn CAD and your explanation of possible ways that you could have done is really awesome!
See my comment above for tips to help expand your 3d cad skills based on the concept you mentioned. Best way to learn is to try the modeling yourself but for example yourself to use these tips to gain an idea of where to start.
I like your videos and contents. I was just replying to some people commenting on your video about your situation due to the conflict that involves your country. In no way do I pretend you deserve to experience this. I just wanted to point out that so many people, most of them innocent, suffer much more on the other side of the border. No personal attacks, no claim to deny the suffering or fear of average people In Israel. Just a sentence to remember how unfair it is for tens of thousands of innocent to be killed by the allegedly most ethic army. I do not hold you accountable for it, it is a general political issue. I think humanity as a whole has interest to de escalate this conflict since it has worldwide impacts and implications.this implies recognizing the other one's suffering too. You do not need to silence my reply to another commentator.

They are human beings too, and are numerous. Nobody deserves to be treated this way. The shame is, the companies from our countries are the ones selling these slaughter tools.
Thomas Sanladerer released a video that was showing off a 3devo shredder and filament maker. Two things from the shredder showcase that might help with your shreddeer that I noticed: 1) Slow feeder so not too much material gets in at once. 2) Every so many rotations, and it is rotating at a slower speed than yours, it does reverse rotations. This would help prevent things from getting stuck.
I agree, the best roi with a 3d printer is being able to design your own custom parts to fix your own custom issues. In our dining room, we had a power strip attached to a table leg with velcro but it kept sliding down and would eventually come loose completely. I managed to design a custom bracket in Fusion 360 and the power strip is now held in place perfectly! A simple but great solution and something I feel proud of lol. My only problem is that my lack of CAD skills is holding me back so far. I have more ideas than I know how to design 😬
Just a thought. Instead of the fan on top to cool and a funnel into a hopper on the bottom to catch shreds. You could use a funnel to a shop-vac and use that as both your airflow source, and hopper. It would provide lots of airflow and be actively pulling the shreds out of the shredder instead of trying to push them through.
I bought some magigoo on a recommendation from a previous video of yours, as I was having some bed adhesion issues with larger prints, where the corners would warp leading to non-level bottom layers. I have to say, it's the best 3d printing accessory I've bought! Everything sticks to the plate perfectly, and I've gone up to about 20 prints before cleaning and re-applying. Tall stuff, wide stuff, right out to the edges of the build plate - nothing phases it. It's amazing the difference it's made to the quality of my prints. Highly recommended 😀 Cheers!
Yeah man. Glad you like it! People are like “it’s expensive,” but then they try it and see how well it works and how long it lasts and they get it! I haven’t tried more than about 10-15 prints on one application but wow, I will try to push the limits more!
I got a 3d printer and while I have mostly printed existing designs, but I have done a few of my own in CAD that have worked well. I use OpenSCAD for it, which is a different way of doing CAD, but I like it and it works well for me.
"Losing time" to learning a new skill is often well worth the sacrifice but hard to justify in the moment. As someone who taught hs robotics kids these skills, 4 thoughts to employ in an either/or capacity: 1) model one random object in your space per week (pick any time interval but stick to it), it's crazy how many operations go into reproducing simple objects. 2) try to design the same part in different ways. Go through building the model once then go back and do the same fart with different types of operations (i.e. revolving an accurate profile vs extruding and cutting. 3)Try to see how few operations you can use to create a given part. Minimizing operations isn't always the best way for ease of modifying the part later but it forces you to try different things, teches how constraints stack and keeps large assemblies from bogging down 4) improve on level of detail, once you have modeled an existing object to design your "fix" part off of (or any part from #1), go back to that part and add in details that you didn't care to model the first time to make it more accurate as you gain proficiency in using different operations. And often that part can then be used for more in the future (i.e. an aluminum extrusion can be just a column then going back it can show the full extrusion profile with accurate dimensions. These 4 techniques will help you learn without feeling like you are investing in time wasting or like you are sinking a bulk of time all at once into learning how to model in 3d. Try building a simple Phillips head screwdriver that you can find in your drawer......
Love this! It is an amazing and unique feeling when you brought something from a thought into reality, that's the feeling that keeps ya going! *looking into putting and inverter in your fan system to reduce amps *
As a hack, if the wire itself is heating, splice in an additional wire near each end for each of the wires, so you have two wires connected where one was. That can handle twice the current. The barrel jack and plug may need to be upgraded if those are heating up too. Replacing with larger wires is the preferred method, but hacks for integrum use are helpful.
I moved from Fusion360 to OnShape. I can tell from this video that I am not as skilled in CAD as you are. I do really enjoy creating in 3D CAD and then having a successful part. Thanks for the video. I did subscribe.
For the shredder the consecutive blades will heat things up by acting like a screw and push material to one side. Change the blade order to more random or flat to stop the effects.
great video as always:) regarding increasing pressure to "push" the particles, axial fans, like the one you use, are very bad at creating static pressure, which is what you want there, air volume is not really a measurement you should care about here:) you could switch to a centrifugal fan, bought or made, either way, it will be a much better fit to your problem in my opinion. and maybe even using some flexible material to create a seal around the edge, that will definitely help as well. and again, thanks for the content:)
Regarding,our shredder, I wouldn't count on that 4mm mesh working. Just revert to a stock 8mm one, and build yourself a mini shredder from printables for that last stage of shredding
As someone suggested, use a shop vac for the shredder. However, if you’re getting a good seal between your funnel and both the shredder and the storage bin. I’ll admit I’m not sure about how much force you’ll need to do this. You could turn it into something similar to a wood shop dust collector. You’d have to model a rubber seal for the bin lid. Then cut a hole in the top to connect the shop vac hose. Or buy a 5 gallon paint bucket with a tight sealing lid.
5:55 There is a difference between tolerance and limits & fits. You model fit-up, as in how one part related to another as they are assembled. Such as clearances between a pin and a hole. Tolerance is how far out something can be manufactured in comparison to the model/drawings and still be acceptable. This is especially important for mass production so that every part will fit with every other part, regardless of who or when it is manufactured.
I've been dipping my toe into designing. Right now, I'm just using Bambu Studio, but I've designed a part to go with a cheap picture frame to use the floating mount I had, a topper for my work monitor pole to attach a toy to, and, my most used thing, a cup holder to fit on the rail of my daybed so I stop knocking my drink off it.
try freezing the plastic before dumping it into your shredder?? Might make the plastic more brittle and help out the process... Also i run a small hammer mill for recycling computer parts, and I’ve rigged it so a waterfall feeds in with the raw material into the top, helping wash everything through. The bin below stays about half full of water, which is great for separating materials-heavier stuff sinks while anything lighter than water floats. Honestly, I wasn’t even thinking about cooling when I set it up. I was just tired of dealing with dust collecting in the corners and floating around my garage.
The first thing I ever printed was a rear assembly for my anet A8. Which I printed on the A8 with a broken rear assembly. Another good practise is asking family and friends if they have small broken things. Switches, knobs hangars stuff like that. Helping people out is always good.
Definitely and it’s a good challenge. I do some CAD work for a local charity for disabled persons and it’s always a great challenge to model stuff for them
@@thenextlayer I am actually disabled. It's complex but the easier part is I have strength and mobility issues in hands. Would be interested to see anything you are doing in the disability space.
I think you may have the solution to your overheating cables, put a hose on the air intake and run the cables inside it. The airflow should cool the cables, all you need to find out is if it is enough cooling and of cause use a hose that do not collapse. Perhaps you can use speed control to find the sweet spot with air flow vs cable heat. If that is not enough, use thicker wires to reduce resistance as well.
For the varipole cable clips, you could smear on a thin coat of Tec7 on the inside and let it dry. It will turn rubber/silicone-like and improve the friction grip.
I wonder if you can add some sort of heat sinks and fans to the exterior of the shredder to cool the metal. Mounting them may require drilling then using a tap and die set to thread the holes. Computer thermal pasts could carry the heat away to the heat sinks more efficiently. The more complex option, if cooling the exterior of the shredder works would be to water cool it with water blocks, a pump, and radiator.
I'd just ditch the barrel jacks and go to Powerpole connectors. As a bonus, it's really easy to design a printable mount for powerpole connectors on the machine so that you can have one end fixed if you want it.
No shade toward Magigoo, but I really love Vision Miner’s Nano Polymer Adhesive. It works for basically every filament people are using regularly as well as advanced materials, all from the same bottle.
Honestly the best thing anyone can do is take a college course on CAD. I took a course in College and learned in a week what would take someone months of “messing around” or trying to learn on their own. I’m sure it’s school and professor dependent but my teacher taught me so much in such a short time it was great. I was also allowed to power through every project for the semester and stop going after finishing them in 2 weeks. Then just came back for the final.
@@thenextlayer really? We had blueprints and drawings we had to make in 2D/3D each week in the intro course. The next 3 courses were again blueprints but 3d solid extruded parts each week. The final was 3 parts needing made with a .002” tolerance with no extrusion errors or tooling failures. Maybe the difference was high school vs college. Because in auto shop in high school it was the same. In college it was much more serious and professional haha
Great Video, Question at time 8:30 you printed the mini quick release standing up on it's side. How do you make sure your part will be printed round as when I print a round part like that on my k1max with petg it's is more oval then round.
Hey I think your shredder teeth might be too coarse to efficiently grind finely enough for the finer mesh you added. I recommend you try a double shredder. Look at industrial shredders for recycling plastics and metals. You might try upper shredder with coarse and teeth. Lower shredder with finer teeth and filter.
How about a vacuum pump on the hopper side? May need a actual filter due to partical size but it would help suck out plastic from the grinder and not only have less material to heat up but more air will move through
@thenextlayer I hope you're all safe, just a quick tip: Learn built in supports, its as easy as having a solid body with a gap of your desired layer height, this makes it so that you decide where support goes and you know exactly where and how it will scar (if at all).
For your shredder issues, as I understand things, the shredder is overheating because it was originally designed to grind to 0.8mm, but you modded it to get down to 0.4? Working on that premise, and realising that there are space and cost implications for this: Would it be possible to create a 2 stage shredding process, where you reinstate the original function of the shredder you have for 0.8mm bits, then funnel the output from the 1st shredder into a 2nd, finer grade shredder, to get the required material size? If there were still heat issues, you could even put a watertight sheath around the funnel from the 1st to 2nd shredders, and water cool the output from the 1st shredder? Or, you could use a PC case fan to do the extraction? I don't know, air displacement wise whether that would work better than the turbine fan, and you'd need to use a mesh to stop the shredded bits flying out of the hopper, which would probably get clogged ridiculously fast... I don't know, but it's a thought? on a related note, can you make watertight gaskets with TPU?
Hey 👋 random viewer here with a random idea from another profession as well as incorporating a couple other ideas. For your excessive heat while shredding I'd suggest something similar to grinding up meat during sausage making. Your idea to get a smaller piece just needs layers. Maybe design a way to switch the different size meshes onto the grinder. Grinding into the bigger size, then switching down and grinding the smallish stuff down to the size you are aiming for. This is essentially what has to be done while making sausages. The meat should ever get warmed during the entire process as this will change the final texture. I think something similar might help. Giving the machine time to cool down in between will probably help. Future idea is that maybe you could invest in another grinder to keep the meshes on at all times and then just more the material from one into another. Also adding in the idea you already commented on about using something like a fresh (thus keeping everything clean stilln hopefully) shop vac to help pull the material through from the other side. Sorry for this long message. I am a ranter. I hope you and the family stay safe.
How does magigoo work with the finer application on the graphic effect build plates? Does it create too much of an interface to get the effect, or does it spread thin enough to maintain it?
Have you considers the idea to Change the box from wood to metal? That should help in dissipate the heat. In that case, if still necessary, you can try to cool further down with some peltier cells. Does this make sense to you?
For the shredder, could it be a solution to do a first shred at 8mm and then shredding it once more at 4mm? I’m guessing that the lesser the effort needed to shred the less the heat, no?
Hi, Jonathan! Are you coming to Formnext, Germany in November, by any chance? Love your videos ❤ This is my field, to design for functional parts, prototyping and inventing and solving problems.
I got an open box bidet for a fraction of the price (>$500 off) and when i got it, it was missing a metal mounting bracket. It took only a few minutes to measure, and hour to model "square with some square cuts", and i couldnt believe how easy it was for how much i I saved. (Even better - the original metal brackets wouldnt fit my toilets wider screws, so i just printed both!)
love your stuff man :) if you ever have time could you see if there is a solution to a problem im having i am craving to make an ams system work with my neptune 3 because i cant afford a bamboo or a voron well if its even possible would love to know if there is a way
FYI - when you are talking about 'tolerances' you're actually describing 'clearances'. There is a difference between tolerance and clearance. I get it that you aren't formally trained in engineering, but little things like this *are* important.
Would there be a way to liquid cool the shredder? Copper that’s thermally interfaced to the device in some way could work. I work in an industrial waste processing facility and our shredders jam when not cooled properly. It looks like it’s a heat soak kind of issue where the plastics are insulating heat generated by friction. Another alternative is that heat pipes and heat sink could be used to wick the heat away as well, joining them to a copper plate on the shredder. Just ideas; but i don’t have intimate experience with the shredder like you do. From my experience it’s friction causing heat soaking This is going off of my assumption that you’ve readjusted the blade positions. You had mentioned that in a previous video; I’m assuming this is just old footage. You likely don’t even have to cool the blades directly. If you cool the assembly on the outside it will passively provide some cooling to the blades.
Also I assume that due to costs; having a second shredder that goes through a smaller screen. Grinding large pieces causes a lot of heat; so when you have such large parts going in it’s going to give way higher temps.
Your shredder blades look about 8mm thick. about the size of the original sift.. for the smaller holes you need thinner blades... with less rechewing comes less heat... 😀
I needed to solve an overheating problem once… my mobile phone was overheating on a wireless charger mount, I used a tube to direct cool air from my air conditioner. it solved my issue. Do you have any air conditioning near by that you could use... hope the advice could help your situation. BTW Stay safe love your content
It's my favorite color alongside black. Twist ties won't hold firmly to the pole in the same place while letting the cable go back and forth, it's either too tight or too loose
@@thenextlayer Lol, that orange hurts my brain. I wasn't referring to your sound cable issues specifically. I use twist ties for everything. Anyway, I'm sorry that I didn't say anything positive. Liked the video. I especially like the suggestion of printing a cutaway for testing which I used to do religiously, although I'm starting to learn my tolerances for my printer now.
one thought I had was getting a second one of those fan's for the shredder, and angling the fans to converge just to the left and right of the center blades, it should help a bit with redirecting the shredded material away from the blower. You may have to find the optimal angle of the fans to still be able to push plastic but not fly directly back into the fans.also putting an extend plastic shroud that extends below the blower fan board and output about 10 cm would also help deflect flying chips
Real world problem: friend got a Nespresso machine. the base where the cup sits is quite small forcing the use of small mugs. She would stand there holding her mug while the machine heated up and then finally made the coffee. I designed a wraparound base extension that allows her to use any mug she has without having to hold it and it looks like it is stock. Any time something affects someone's ability to make coffee i take that extremely seriously.

The first thing I ever printed was a rear assembly for my anet A8. Which I printed on the A8 with a broken rear assembly. Another good practise is asking family and friends if they have small broken things. Switches, knobs hangars stuff like that. Helping people out is always good.
Definitely and it’s a good challenge. I do some CAD work for a local charity for disabled persons and it’s always a great challenge to model stuff for them
@@thenextlayer I am actually disabled. It's complex but the easier part is I have strength and mobility issues in hands. Would be interested to see anything you are doing in the disability space.
Great video. Messy studio is great too!
I think you may have the solution to your overheating cables, put a hose on the air intake and run the cables inside it. The airflow should cool the cables, all you need to find out is if it is enough cooling and of cause use a hose that do not collapse. Perhaps you can use speed control to find the sweet spot with air flow vs cable heat. If that is not enough, use thicker wires to reduce resistance as well.
For the varipole cable clips, you could smear on a thin coat of Tec7 on the inside and let it dry. It will turn rubber/silicone-like and improve the friction grip.
Good idea I have some plastidip
I wonder if you can add some sort of heat sinks and fans to the exterior of the shredder to cool the metal. Mounting them may require drilling then using a tap and die set to thread the holes. Computer thermal pasts could carry the heat away to the heat sinks more efficiently. The more complex option, if cooling the exterior of the shredder works would be to water cool it with water blocks, a pump, and radiator.
12:05 Try adding some gaffer's tape to the inside of the cable clips and see if that's enough friction to keep them from moving around.
Good idea!
what is the chance of shredding at 8mm first and then shedding the 8mm to 4mm?
I'd just ditch the barrel jacks and go to Powerpole connectors. As a bonus, it's really easy to design a printable mount for powerpole connectors on the machine so that you can have one end fixed if you want it.
No shade toward Magigoo, but I really love Vision Miner’s Nano Polymer Adhesive. It works for basically every filament people are using regularly as well as advanced materials, all from the same bottle.
I’ve heard it’s very good too. Haven’t tried it though
Honestly the best thing anyone can do is take a college course on CAD. I took a course in College and learned in a week what would take someone months of “messing around” or trying to learn on their own.
I’m sure it’s school and professor dependent but my teacher taught me so much in such a short time it was great. I was also allowed to power through every project for the semester and stop going after finishing them in 2 weeks. Then just came back for the final.
I did 2 years of CAD in high school and spent the entire time dicking around with friends and tracing pictures LOL
@@thenextlayer really? We had blueprints and drawings we had to make in 2D/3D each week in the intro course. The next 3 courses were again blueprints but 3d solid extruded parts each week. The final was 3 parts needing made with a .002” tolerance with no extrusion errors or tooling failures. Maybe the difference was high school vs college. Because in auto shop in high school it was the same. In college it was much more serious and professional haha
Great Video, Question at time 8:30 you printed the mini quick release standing up on it's side. How do you make sure your part will be printed round as when I print a round part like that on my k1max with petg it's is more oval then round.
Hey I think your shredder teeth might be too coarse to efficiently grind finely enough for the finer mesh you added. I recommend you try a double shredder. Look at industrial shredders for recycling plastics and metals. You might try upper shredder with coarse and teeth. Lower shredder with finer teeth and filter.
Yea I think that’s true. The whole thing is kind of a fail I’m not gonna invest more into it honestly.
How about a vacuum pump on the hopper side? May need a actual filter due to partical size but it would help suck out plastic from the grinder and not only have less material to heat up but more air will move through
You might want to try finding a grinder that has some more space between the blades and housing, making the pieces not get rubbed along the sides
@thenextlayer I hope you're all safe, just a quick tip: Learn built in supports, its as easy as having a solid body with a gap of your desired layer height, this makes it so that you decide where support goes and you know exactly where and how it will scar (if at all).
For your shredder issues, as I understand things, the shredder is overheating because it was originally designed to grind to 0.8mm, but you modded it to get down to 0.4?
Working on that premise, and realising that there are space and cost implications for this:
Would it be possible to create a 2 stage shredding process, where you reinstate the original function of the shredder you have for 0.8mm bits, then funnel the output from the 1st shredder into a 2nd, finer grade shredder, to get the required material size?
If there were still heat issues, you could even put a watertight sheath around the funnel from the 1st to 2nd shredders, and water cool the output from the 1st shredder?
Or, you could use a PC case fan to do the extraction? I don't know, air displacement wise whether that would work better than the turbine fan, and you'd need to use a mesh to stop the shredded bits flying out of the hopper, which would probably get clogged ridiculously fast... I don't know, but it's a thought?
on a related note, can you make watertight gaskets with TPU?
doe any one know the name/ model for those small LED light that he showed in the video at 7:26?
Hey 👋 random viewer here with a random idea from another profession as well as incorporating a couple other ideas.
For your excessive heat while shredding I'd suggest something similar to grinding up meat during sausage making.
Your idea to get a smaller piece just needs layers. Maybe design a way to switch the different size meshes onto the grinder. Grinding into the bigger size, then switching down and grinding the smallish stuff down to the size you are aiming for. This is essentially what has to be done while making sausages. The meat should ever get warmed during the entire process as this will change the final texture. I think something similar might help. Giving the machine time to cool down in between will probably help. Future idea is that maybe you could invest in another grinder to keep the meshes on at all times and then just more the material from one into another.
Also adding in the idea you already commented on about using something like a fresh (thus keeping everything clean stilln hopefully) shop vac to help pull the material through from the other side.
Sorry for this long message. I am a ranter. I hope you and the family stay safe.
Good ideas thanks I’ll try to put them into practice
How does magigoo work with the finer application on the graphic effect build plates? Does it create too much of an interface to get the effect, or does it spread thin enough to maintain it?
I got my printer solely for functional enclosures. One of the best things i printed was a phone case, saved my phone more than 10 times
Yoni...question....do you have PLA adhesion issues on your Bambu printers?
PETG sticks like glue, it's hit or miss with PLA (PEI plate)
Perfect, good job 👍..but I see why most content creators have crane system on the ceiling..
I’m sincerely wondering. Is the fan creating positive or negative pressure? I want to say positive pressure because it is pushing air into the hopper.
Oh yeah good point I wasn’t thinking.
Have you considers the idea to Change the box from wood to metal? That should help in dissipate the heat. In that case, if still necessary, you can try to cool further down with some peltier cells. Does this make sense to you?
To make the turbine fans spin backwards, you have to swap two of the three wires between the controller and the motor.
For the shredder, could it be a solution to do a first shred at 8mm and then shredding it once more at 4mm? I’m guessing that the lesser the effort needed to shred the less the heat, no?
Love your channel!
יש סיכוי שיש לך hotend ספייר לsv08??
Yeah I have the heat sink and extra nozzles. Message me on discord
Hi, Jonathan!
Are you coming to Formnext, Germany in November, by any chance?
Love your videos ❤
This is my field, to design for functional parts, prototyping and inventing and solving problems.
I should be there yeah!
I got an open box bidet for a fraction of the price (>$500 off) and when i got it, it was missing a metal mounting bracket.
It took only a few minutes to measure, and hour to model "square with some square cuts", and i couldnt believe how easy it was for how much i
I saved. (Even better - the original metal brackets wouldnt fit my toilets wider screws, so i just printed both!)
at first i was like bro TMI and then your comment turned out very relevant lol.
love your stuff man :) if you ever have time could you see if there is a solution to a problem im having i am craving to make an ams system work with my neptune 3 because i cant afford a bamboo or a voron well if its even possible would love to know if there is a way
add foam tape to the inner surface of the varipole cable clips for friction
you might also try periodically shaking or striking the 4mm screen instead of using pressure
I’ll try this. Maybe.
I use purple glue sticks for bed adhesion and it works perfect for all materials.
But it’s messy and mars your prints.
3:35 you could have made a gravity gimble setup to hold the camera level
FYI - when you are talking about 'tolerances' you're actually describing 'clearances'.
There is a difference between tolerance and clearance. I get it that you aren't formally trained in engineering, but little things like this *are* important.
Thanks! I’m still learning and appreciate the instruction
I would an XT60 connector for the turbine fan rather than a barrel jack. An XT60 is capable of handling approximately 60AMPS
Ever considered a "meat grinder" principle for the shredding ?
Why not consider doing the shredding in 2 (or more) phases? Do a pass for the intended 8mm sieve, then another for the 4mm
Would there be a way to liquid cool the shredder? Copper that’s thermally interfaced to the device in some way could work. I work in an industrial waste processing facility and our shredders jam when not cooled properly. It looks like it’s a heat soak kind of issue where the plastics are insulating heat generated by friction.
Another alternative is that heat pipes and heat sink could be used to wick the heat away as well, joining them to a copper plate on the shredder. Just ideas; but i don’t have intimate experience with the shredder like you do. From my experience it’s friction causing heat soaking
This is going off of my assumption that you’ve readjusted the blade positions. You had mentioned that in a previous video; I’m assuming this is just old footage.
You likely don’t even have to cool the blades directly. If you cool the assembly on the outside it will passively provide some cooling to the blades.
Also I assume that due to costs; having a second shredder that goes through a smaller screen. Grinding large pieces causes a lot of heat; so when you have such large parts going in it’s going to give way higher temps.
Your shredder blades look about 8mm thick. about the size of the original sift.. for the smaller holes you need thinner blades... with less rechewing comes less heat... 😀
I needed to solve an overheating problem once… my mobile phone was overheating on a wireless charger mount, I used a tube to direct cool air from my air conditioner. it solved my issue. Do you have any air conditioning near by that you could use... hope the advice could help your situation. BTW Stay safe love your content
It's far, but I could try that lol
@@thenextlayer add an inline fan if you need need extra long ducting. LOL
Would running water through the shredder be a possibility?
It makes the stuff get even more stuck
Hope you had a good vacation.
ty good reference episode
19:23 Okay, I'll bite. How do you know?
🤣🤣🤣
Try lubricating the blades with something you can wash off with isopropyl alcohol
Good idea. Such as??
Slow down the shredder motor?
link to turbine fan?
Same question here :)

Added to description too.
Just use water to to cool down plastic. Dry plastic later. No problems with heat after that. Water Shredder.
That makes it get even more stuck in the siieve!
The secret product is a secret that isn't known to people who don't know what the secret product is.
Why do you use orange so often? Also, seems like a twist tie could have solved some of these.
It's my favorite color alongside black. Twist ties won't hold firmly to the pole in the same place while letting the cable go back and forth, it's either too tight or too loose
@@thenextlayer Lol, that orange hurts my brain. I wasn't referring to your sound cable issues specifically. I use twist ties for everything. Anyway, I'm sorry that I didn't say anything positive. Liked the video. I especially like the suggestion of printing a cutaway for testing which I used to do religiously, although I'm starting to learn my tolerances for my printer now.
Try putting your used plastic in the freezer for a while before shredding. It should shred better, not melt, and even cool the tool.
Oh damn that’s a good idea. I don’t have a shredder at the office though.
@@thenextlayer a shredder? A freezer?
Barrel jacks stink! Try xt60 or xt90 connectors. They can candle up large amps. I use them for everything low voltage (5-60v) but high amp (20-50a)
one thought I had was getting a second one of those fan's for the shredder, and angling the fans to converge just to the left and right of the center blades, it should help a bit with redirecting the shredded material away from the blower. You may have to find the optimal angle of the fans to still be able to push plastic but not fly directly back into the fans.also putting an extend plastic shroud that extends below the blower fan board and output about 10 cm would also help deflect flying chips
i really need to shift to onshape
Your shredder is turning everything to dough? So… you’re making PLA-dough? 🗿
Hahahaha good one.
2:58 Steve Buscemi???!!!
Real world problem: friend got a Nespresso machine. the base where the cup sits is quite small forcing the use of small mugs. She would stand there holding her mug while the machine heated up and then finally made the coffee. I designed a wraparound base extension that allows her to use any mug she has without having to hold it and it looks like it is stock. Any time something affects someone's ability to make coffee i take that extremely seriously.
I printed one of those too a long time ago!
I also made one of those, genuinely don’t understand why Nespresso doesn’t do it themselves
And another advantage fact you can print as many parts as you have filament, one after another, on the belt…?
Yup
Great video, as always. Just wanted to say we love Israel. Sending love from Iran.
having 3d printer without knowing how to model in some CAD software is like having a car, but you dont know how to drive it
