My journey to make an extremely effective 3D-printed dust collector for my CNC router-and a summary of the previous iterations that didn't really work for me.
Final router design features a circular ring of magnets that let the user easily change orientation in order to avoid hitting fixtures as needed, and easily remove to change bits.
STL files available here: github.com/Jer...
Will also need 10-24 screws (and tap) as well as 12mm circular rare earth magnets.

Finally, thanks to Ron at Romaxx for pointing out that the exhaust of my router was likely interfering with the clear collector's suction!

You gave me a heart attack cutting onto that 2x4 with the carriage bolt still inside
Hope you are recovering ;-)
If you're referring to around 1:30 I meant that the carriage bolt goes in after drilled out.
I'd invite you to check out the next version here: th-cam.com/video/BHew18YmPYI/w-d-xo.html to see how things developed!
@@JeremyCook No dude I'm talking about at 5:45! You're cutting into the old 2x4 dust boot and the carriage bolt is still in there. I do like the dust collector you ended up with, my garage machine has something similar.
@@davidriedell5938 Ah, right. Good catch, I probably should have taken that out before. Glad you like the design, it's worked really well for me!
I'll have to keep that magnet system in mind in the future. I bet it can be used for a variety of purposes. I also liked the quick overview of the failures leading up to the final one. I learn a ton from what hasn't worked for others and not many people show their mistakes.
Thanks! I'm a big fan of rare earth magnets, so many uses.
Glad you enjoyed the mistakes. I think it's an interesting editorial question as to whether or not to show them. On the one hand, it seems interesting here to show different approaches. On the other hand, showing ever nail I missed (figuratively here) wouldn't really do anyone any good other than to show that everyone makes mistakes.
One could make an argument either way, and you definitely see it both ways in other peoples videos!
Jeremy S Cook I guess the main reason I liked it is that you showed making something from start to finish and it didn't work and explained why and how you improved it. You're going through an iterative process. If you were making a desk for example and made a mistake on something small like a drawer I wouldn't be as interested in watching that part.
Makes sense, I'll have to keep that in mind for the future!
I had originally considered making the wood block a video of its own. Glad things worked out to give the main project a bit more background.
Great design; I really like the shunting of the routers built in air blast to help keep the area around the bit in upwards suction. Very few other designs do this and it seems like such a great optimization.
Thanks! I've been quite pleased with it.
It's something like my 5th try at this type of device, so I guess practice makes perfect (or at least better)?
Love the idea with the magnet detents!
Thx Ryan! Planning to be at Maker Faire Orlando this year?
@@JeremyCook good question, we didn't realize it was coming up! We should probably show stuff there but it looks like the deadline for submissions is just a could days away
You could always wander around in your flight suits, guessing someone would recognize you!
That is a great result! I found that it only works on mine with a baffle around the perimeter. But your solution right around the bit is great!
Thanks! I had another idea for putting a brush around the perimeter of the suction fixture, but so far I haven't needed it.
Also, thx for the idea to print it in two pieces. Worked out quite nicely!
sincerely, you have made the most efficient cnc dust collector that I've seen around. Great work! I will try to make it using plywood as I don't have a 3d printer. The magnets are nice but I don't have too much space around so I'll have to stick it manually, but that's not a problem. many thanks for the idea. In the future I will contact you with some ideas and improvements (if I can manage to get any)
Hi William, glad you liked it, and hope you're able to make one! If it would help you, I've actually got part of one that you can have if you want to pay for shipping: twitter.com/JeremySCook/status/1163618514051223552 (not sure where you live, some places get pretty pricey).
Hope you enjoy the video as much as I enjoyed making this!
Let me know what you think about the 3D-print time-lapse sequences. I need to get things tuned in properly (and maybe use my DSLR instead of the Pi V2 camera), but I think this technique using Octoprint/Octolapse has a ton of potential!
Jeremy S Cook I liked them. I think they took the right amount of time. Any slower and they might get boring.
Nice, thx. Figured out how to focus the camera, so the next iteration will hopefully look a bit better.
I use Octopi and love the time lapse videos. Yours are great.
Well thanks! Hoping they improve as I figure out how to use it better.
I love the look of that filament!
Hey Tyler - I agree, it's a great material, especially if you don't want to paint it!
Great design you're the only other person besides myself that has a addressed the air flow from the router causing problems I think I'll look into your design and add a broom at the bottom thank you for the video
Well thanks! Would love to see how it turns out.
Found you from Hackaday. Well done! Something you could consider for even more effectiveness is to add a perimeter brush around the rear half of the suction opening. That way you still have full visibility from the front but double the airflow.
Thanks for checking it out Russ. Certainly something to consider - perhaps I'll eventually do a "Rev1" with this and a few more ideas integrated!
Nice work. I'm designing one at the moment. I'm planning to put the house attachment on the 'top' side that bolts to the spindle so that the magnets don't also require clamps. Less flexible in terms of hose position but I think I can live with that.
Very clever. I may have to use that concept if I made another iteration of it!
Really helpful!!! It's amazing how clean the work area ends after milling the pieces. Nice work.
Felipe López thanks!
Perfect. I was just contemplating on how to make something similar for my little 3018 CNC
Awesome, I'd love to hear your results! Also, check out the improved version here: th-cam.com/video/BHew18YmPYI/w-d-xo.html
This is a great design, I love how it adjusts and can be easily removed!
Thanks!
Off subject here but get yourself some down cutting bits and the plywood cuts will come out much cleaner with much less tear out. Just two cents worth and nice dust collector boot.
Np, thanks for the tip, and glad you enjoyed!
I bought a Maslow CNC that I still have yet to set up. Once done I'll be looking to see if I can use you design on it! This is awesome! Thank you for sharing!
Thanks so much for your kind words! I'd love to hear how it turns out.
I loved this video Jeremy! The detents with magnets is genius! Perhaps you can build-in some clamping mechanism into this system where you insert a rod to prevent rotation instead of the clamps. Even with the clamps this is just too cool. Great job as usual!
Thanks Keith! That is a good idea - unfortunately it's not the rotation so much as the weight of the vacuum pulling it down and off. Guess I should have shown that :-)
Well now that makes sense.
Seems like it would be cheaper to just use nubs and divots since you are clamping it anyway.
You can use the "tab" feature in fusion 360 when doing your CAM to keep small parts from flying away. It's found under 2D contour
Thanks! Made a good video clip at least ;-)
Gunna leave this here th-cam.com/video/jHbI_B2sPA0/w-d-xo.html
Very inventive!
Thank you!
Best working dust boot I’ve seen on TH-cam. I don’t have a 3D printer.. can the print files be imported into Aspire? With some work I think I can make this on a cnc router.
P. S. Do you really need the spring clamps? With good rare earth magnets should not need.
@@unclebob8746 Thanks!
So to answer your first question, I'm not sure, I've never worked with that program. Would be tough on a router IMO, but perhaps possible.
I didn't think I'd need them, but my setup does. If the walls were thinner, maybe not. Also, there are some files on the GitHub page that have a clamp setup that may work better.
Nice job Jeremy! Really can't see any dust at all.
Thanks! Definitely happy with how it turned out.
..great design..love it
Thanks!
Cool project! We're you able to recover the stew that fell out and got sucked up while everyone was distracted looking at it sucking up the work piece? Testament to the awesome suction!
And by stew of course I mean screw....
Not sure why I just saw this - anyway I'm not sure at this point. I'd guess I just used a spare. Thx for commenting :-)
Awesome work! Thanks for sharing. What type of shop vac do you use?
Thanks! Using a Rigid "Shop Vac" from Home Depot.
Since you enjoyed that, be sure to check out part 2: th-cam.com/video/BHew18YmPYI/w-d-xo.html that features an improved version.
I love the magnet detents! Are they not strong enough to keep the whole thing from rotating during a milling job? The whole thing seems kind of ruined by the need for clamps.
Hi Michael - not so much rotation, but the offset weight of the vacuum hose ends up pulling it off.
I was pretty disappointed when the magnets couldn't hold it by themselves, but I was glad I at least got it to work with the clamps. Probably could use stronger/more magnets.
It's certainly less slick with the clamps, but I wouldn't call it "ruined," as its still quite effective and convenient.
You're right, "ruined" was the wrong word. It's still very functional obviously, but it takes away from the epic aesthetic.
Could you possibly make a clamp for the vacuum hose somewhere up at the top of your spindle so as to remove the weight of the hose from the dust collector assembly? Sort of like a strain relief for the vacuum hose?
Yeah, figured you didn't mean that exactly. Thx for classifying it as having an epic (or almost so) aesthetic!
Didn't think of that - that's a good idea. Maybe I'll think of some way to do that without taking away from the functionality of being able to remove the hose and/or fixture as needed.
Nice build! How deep can you cut? Is the height adjustable?
Thanks! Cutting depth depends on the material, but it's not restricted by the dust collector (or at least minimally). The ring that clamps on to the router can be adjusted I suppose, but its not really meant to be.
Did you notice the off-balance-vibration condition (@7:23) caused a screw to fall out?
I did. Thought it was interesting to leave in there. Was using shorter screws than I wanted, so didn't have them tightened down too much. Now replaced with longer button head screws.
Will you be sharing this on Thingiverse eventually? Brilliant!
Hey Dave, thanks, I've been quite pleased with the results! I've got a change or two I want to make, but will likely put the STLs up eventually. (prob. another platform though)
@@JeremyCook just let me know where and when :). I can wait.. While I have movement I don't have my limit switches on yet and I still have to adjust my settings
I'll try to remember, but if not, check back in a week or two and hopefully I'll have something in the description here.
Here you go: github.com/JeremySCook/DustCollector-DC0 made some minor changes, so LMK if you have any issues.
Thanks Jeremy - Ill try to print one early next week
Buen día lo felicito excelente
Gracias!
Is there a single piece version for those of us with larger printers? It would save us a step!
Haven't published it yet, but plan to soon. Check back in a week or so, and if you don't see it on GitHub, please ping me again.
Here you are: github.com/JeremySCook/DustCollector-DC0/blob/master/SinglePiece-DC0.stl
I was interested too. Thanks a lot ! Will print that ASAP
Nice. I'd love to hear how it works for you!
That’s a really nice design ?.
Thanks!
At 6:19 I like how you lost a bolt
Yeah, got a couple screws loose ;-) - works pretty well now that things are tightened down. Check out the second video th-cam.com/video/BHew18YmPYI/w-d-xo.html to see how the design has progressed!
do you think it is possible to have the original files as i want to modify it to adapt to a makita RT0700C which is smaller and the blocking button is trickier.
but definitevely one of the best designs.
Hi Sebastien. Sorry, I'm not releasing the design right now. Ask me in a month or so, I may release it eventually.
@@JeremyCook ok too bad, I made a little modification with the help of the stl files but from what I see with your video and the 3d model of a Makita, I see that the collet is far away from the body compared to the DeWalt.
So I think I will rebuilt from scratch but keeping the overall design.
Just to be sure the part that is around the collet it touches on the up side the body? ( So it won't suck air from above)
@@SebastienChedalBornu Yes that is correct.
Tell you what, send me your email address and I'll add you to the project when I get a chance. If you can send me the resulting STLs when you're done I'll add it to the GitHub directory.
The model isn't organized very well though TBH.
is thhere no danger of melting the 3d printed part because the spindle gets hot ?
Hi Martin - I haven't had that problem or heard of anyone else experiencing it, but I suppose it's possible.
Any chance you can post STEP files of the CAD design?
Hi, wasn't planning to post the STEP files, but STLs should be in the description.
Would you be willing to share the file?
STL is linked in the description if that is what you need.
Couple of major design flaws, but turned out quite nice.
Dodgy Brothers I see. What would those be?
The biggest is probably the joining of the top piece to the bottom piece. The magnets are too far apart to effectively hold the two pieces together under work conditions. The moment you start moving the X and Y axis the hose on the vacuum is going to try and lever the bottom piece off.
This meant you had to add external clamps to give it sufficient holding force while in use. There is an easy way to overcome this design problem. Well actually there are two ways... The first would be to use neodymium magnets that have a hole in the middle of them that allow you to screw the magnet to the top and bottom faces, which would increase the magnet holding force substantially. As you no doubt spotted the further the magnets were away from touching each other the holding force decreases logarithmically as distance increases.
The second way would have been to design a bayonet style fitting into both parts. You could still retain the multi angle fitting (by having a multi way bayonet), but instead of using the magnet to hold the weight of the bottom part, the bayonet fitting would do that, and the magnets only function would be to stop the vibrations from unclipping the bayonet fitting during operation in the locked position.
Also because the vacuum hose is moving with the machine the hose is adding its own sideways movement to bottom part trying to knock it off. If you designed the vacuum hose to fit to the top piece which is bolted to the spindle that sideways movement is negated because it is solidly locked to the spindle, making the bottom piece require less holding force since it would no longer have that sideways movement.
Couple of other little things but that is the biggest problem.
Thanks for elaborating.
You probably want to look at the air intake size as well. Vacuums work on air volume rather than negative pressure (because they are not a positive displacement pump) Restricting the intake size will increase noise and the vacuum motor temperature. You ideally want equal, or slightly more flow in than the size of the hose.
I currently don't have a dust shoe on my CNC so I am drawing one up now.
Interesting, thanks. Overall I've been pretty happy with the results, but all things to consider if I do make another version. Seems that the perfect dust collector is a never-ending quest!
Hi can you share the Fusion 360 Project?
Not right now. Any suggestions for how it can be improved?
No, i want to try to change the file for an other holder on my machine.
I see. If you need an adjustment for your hose or router, I might be able to do that for you, but I'm not releasing the Fusion file right now.
@@JeremyCook Could you make a version that works with a dewalt 618 and a 2.5 in vac hose?
@@linkreincarnate9402 Hi - what's the main diameter of the 618? Check out the GitHub on the design as there are several variations.
