- To get the best out of 3D printing, it helps if you can design your own parts. In this tutorial series, we will learn to use a free 3D CAD program to do just that.
In this episode, we use lofts to to join odd shapes and then hollow the solid body out. This is ideal for heating or cooling ducts, or making adaptors between two different objects.

retired engineer here with a a short bits of advice on ducts and airflow WRT printers, cuz I see a lot of mistakes being made in the 3DP community:
1. muffin fans do not have pressure capability, meaning they can't push against ANY resistance at all. So the slightest restriction, bend, friction, or reduction in cross section in any duct connected to a muffin fan will utterly destroy that fan's airflow. That especially means 4in flexible drier hose.
2. the air coming OUT of a muffin fan exits in a hollow, wide CONE SHAPE, coming out at roughly a 45º angle. These fans are intended to exhaust into free air through a circular wire finger guard.
Ducts which connect straight to the fan edges, even if wide open, force the air to bend, and that slows it down. So if you must use a duct with a muffin fan, one with a bit of a double curve - first outward, then back inward - at the exit surface (requires a bulge much larger than 120mm on a 120mm fan) will help this problem a lot, but it uses more filament, and it's larger.
Grills (finger guards) with any square edges at all, or rough surfaces, or non-circular shapes, will dramatically hamper air flow. Why circular? The air coming out is rotating too. Use circular wire grills, they're cheap. Use muffin fans to PULL air, not to PUSH air.
3. If the ability to work against resistance (a long duct, or flexible hose with uneven surfaces such as "drier duct") or bends or other restrictions, use a blower. A blower is not a fan and a fan is not a blower. Blowers are designed to work against resistance.
This makes my transition to onshape more pleasant.
this is one of the greatest tutorials I have ever seen on youtube, thank you this is GOD TIER
THIS has now turned me on to Onshape. Thanks so much Michael... excellent tutorial!
Fricken love this dude!
Perfect Tutorial whilst also showing what you can use it for!
Keep it up man!
I was searching YT for a good tutorial on how to desing a fan duct, you cut straight to the point! Now I just need to apply the same techniques on F360 where I'm more used to.
Thank you so much for all of what you make for the 3D Printing community!
An interesting thing I've found through my own experimentation is that wrapping PLA parts in aluminum tape can do a surprisingly good job of protecting them from heat. I've got the ducts for my part cooler set up using that and between the tape on the outside and the cool air flowing through them, I haven't seen any sagging at all. Yet another part slightly further away that I didn't put the tape on ended up drooping after only several hours total print time. Of course this only protects against radiative heat loads but it's a neat trick that seems to work so far for me. Sometime I should do some tests to see how well it works in a more scientific fashion...
these tutorials are so dense I need to watch them a few times to get everything. Thank you for this series! Lifesaver!
I guess I just need to learn a little more patience. I'd decided to start following your last video and design a pegboard holder for sharpies. Worked through the main part of the body in a couple hours, mainly by brute forcing it. Then proceeded to absolutely slam my head against the wall for the better part of two days trying to figure out how to make the top pegs curved. Excellent work as always, boss, and can't wait to see the rest of the videos in this series.
Ah dude! Awesome! I just used OnShape to model and 3D print a plug to then mold and make a carbon fiber air box lid for my GT350. Thanks for the tips!
badass. make a video man
@@janzugic6798 I did. Currently the latest one I did on my channel.
Lol, Ive just spent days creating a twin fan hotend on Tinkercad and then you show me what onshape can do. Pretty cool.
Thoroughly enjoying this series. You're making Onshape seem so easy to get into, and now I REALLY want to get myself a 3D printer.
Awesome tutorial! I appreciate how simple and straight forward the explanations are. Thank you!
This video is amazing and taught me (who learned on traditional 2D CAD decades ago) so much that I have been struggling to figure out in OnShape. Great tutorial, man.
Incredible series, thanks for making this. Can't wait to see what's next
Grabcad is top notch i many times need a part of a project and i go there and look for a final version or something like that, i get just the part that i need 100% recommend
This is a great basic tutorial to have available. I have needed so many duct adaptors over the years and could have used this tutorial to simplify things. Great job. Very useful in many situations.
I just started using Onshape and love it! I really appreciate you making videos that explain how to use the various features of the program. Very helpful!! Thank you!!
Great video! I'm glad you used such a practical example and even showed various ways to modify it to fit similar purposes. I was just looking at designing my own custom fan duct to fit my heavily modified Ender 3 Pro because with all of the modifications to the X carriage, none of the available designs fits just right. I saw the simple ducts you have on your 5050s in your videos and I plan to go with a similar design. Thanks for the inspiration and the instructions!
Great video. I really appreciate the detailed examples for OnShape. I design and print a lot of accessories parts for our drones using knowledge from your channel. Thank you!
Thanks again, what a great series this is becoming!
Ducts are the ideal topic for this video; loft and shell commands make short work of producing something close to what you need, and are great at fine-tuning the final design. My first experience of this was designing an extraction duct system for my bandsaw. It attaches magnetically to the underside of the table, and meanders past guides and brackets to a support where the vacuum system attaches. Very satisfying... it taught me a lot, and you have taught me some more today!
Thanks for all of your Videos, always clear and informative, this Onshape/Loft was just what I was after, keep up the good work. Paul.
I have tried to get on Onshape twice since watching your last video and I have yet had any joy doing it. I will continue to try until it works.
Thank you very much! I’m looking forward to designing my own parts. I’ve been 3D printing for years now but I’ve done very few designs of my own. This is very helpful.
Fantastic tutorial, Michael! Thanks a lot! 😃
Stay safe there with your family! 🖖😊
I've been using onshape for about 3 years now and just got schooled, excellent video Michael
Loving these tutorials.
Good pace, and clear (no waffle). Get the info or rewind if you missed it, far better than the slow laborious lectures that are so common.
@3:35 When you import that step file, you can choose the composite part option (bottom check box) to have it import any assembly step files as if it was 1 part. Very useful for parts like that fan which have multiple bodies, but as far as we're concerned are more useful as a single part. Then when you derive it afterwards, you don't need to transform anything and it will be ready to go
you can also click the parent and it'll import all of them in the way they are in the step file, but you can move them separately
I've been trying to do this sort of thing in Fusion for a while now and this helped me through figuring it out!
Great tutorial, something very practical made relatively easy, well done
Thank you so much for these videos! I use fusion 360 but your ideas are really great, thank you so much! Much success for your channel!
Thanks for this tutorial and the series. I am following along trying to learn CAD. This is a great resource.
Amazing work as always Micheal I look forward to next video 👍👍
What a wonderful video. So clearly explained and a great reference which I am certain I will use in the future!
Great series! Need more CAD tutorials directly related to 3D printer upgrades
Woooooooow I needed that tutorial so much !! Exactly what I wanted. Cheers man
That was awesome! I'd love to see a more in-depth duct design class in the future. Maybe even with the air flow in mind.
Loving your work, thank you and please keep going! Top notch!
I have only used onshape for very very basic modelling and I thought it was alright, but holy cow this video was showing me a simple way to do something every 30 seconds! I had no idea how to do smooth curves or all the tools, this was soooooo helpful
I am sold... been looking for a program to learn and it looks like it will the Onshape. I started learning with you when I had my ender 3 and now with a business I need to learn to design more parts myself. Looking forward to your series.
another great video for this series. cant wait to see more
Wow that move face tool is really nice. Been using onshape for a bit but have not used that. Nice video, thanks!
I can recommend the Create Part Studio in Context feature of the assembly view. It allows you to isolate concerns in a clean way.
very nice tutorial, congratulations for hitting 400k subscribers!
Thanks for sharing and explaining this concept.
Thanks! I have been useing Fusion 360. This is way easier and perfect for the utilitarian projects I normally do. Im quitting fusion and you saved me $300 on the renewal . Thanks for the valuable info. Ill buy lunch! ( this tip was for the OnShape recommendation and tutorials)
This is something that i have struggled some time... trying to do air-vents for car brakes from fog light hole, thanks all the tips, and awesome channel overall
Nicely done! We get used to clicking icons at the top of our applications but when you confront a group of icons that have no meaning it is a bit of an awkward journey. This explained a lot. There is always a progammer's paradigm that you must adapt to be successful. I remember when Photoshop came out with its similar icons to Windows tat did very different things - that was a bit of a transition. It was like having to unlearn how to tie your shoes. That said, the 3D world is coming on strong. ime for a new learning curve!
Thanks man , you made it look very easy , well made video ,excellent teacher, excellent tutorial.
Wow, I was just thinking about re-designing a new part cooling fan shroud for my old Craftbot 4M in Fusion360. I think I will give Onshape a try! Thanks for the awesome content, per usual.
Fusion is almost the same in this regard, all the functions shown are the same, only the buttons and or steps you have to do are different.
I previously used F360 to design some, and while it does work, I had a lot of trouble getting the lofts to work well. The interface in Onshape seems much more approachable to a hobbyist.
Excellent tutorial, with lots of handy info.
Thank you Michael, that was every bit as good as I thought it would be! 😃👌👍
Definitely going to try to use what I learned to duct the air from the one big blower in my Bambu X1 to both sides of the bed.
Awesome video Michael. Thank you!
I really like this series you are making, Michael. I usually watch your videos because you have interesting content but in this case I was actually strugling with the limitations of my 3d design software (Tinkercad+freecad+OpenSCAD) and what you've shown so far covers exactly the kind of things that are experience changing when switching to an unknown (for me) new software like OnShape. Thank you very much. I already redesigned my 3d printer from scratch and this few days I've been finding new ways to improve on my designs with onshape and your tutorials. Cheers from Argentina, mate.
just get the fusion 360 hobbyist license
@@orhansenglish Fusion360 doesn't work on Linux :(
@@tomich6430 there are workarounds for linux y'know
Go with whatever you like. I use Fusion 360 today but I find it cumbersome for the simpler things I generally work on. I'm going to start using Onshape from now on.
Awesome tutorial, thank you Michael for making it ! greetings from Germany :)
extremelyyyyy useful!
Beautifully explained with no wasted moments! I look forward to more in this series. Well done!!
Very nice presentation, that helps people forward.
Damn, thank you for doing these Onshape videos. Tinkercad has been far too limiting but all of the other software I tried was way too complicated.
This is good stuff, thanks for teaching!
Thank you 👌 solved some issues I’d been having for sometime 👍
I like this tutorial style video format
Excellent video and just in time because I need to make some custom fan ducts!
I was unable to complete the loft at 8:40 because the profile on sketch 3 had "inner loops", the inner square marked in red as the culprit, not sure what I did wrong at first but noticed OnShape uses the extruded part's edges as if they were part of the sketch so I tried redefining the plane of the sketch as normal plane instead of the part's face and it worked. This is not an issue in the video for some reason despite the edges I mentioned showing up too as far as I can't tell, don't know if it's a quirk of OnShape or just me being used to 360 and its own quirks.
A small related suggestion: Being the second project in the series it would have been better to go into more details about how the platform sketches are defined, I had to figure out some of the reference points and geometry based on the very quick rundown on the video, so that's likely the source of my problem.
You might have used the loft function on the sketch and extrude, use it on sketch and sketch instead, might help!
@@solish3458 thank you, I worked around it by redefining the sketch plane a couple times but now that I'm more familiar with OnShape I think that's probably what happened (for anyone else reading this, keep in mind you can specifically select the sketch in the Features list instead of clicking on its profiles). Also sketch "imprinting" kept biting me throughout the tutorial series, so disabling it might have helped too.
thanks a lot! that is exactly what i was looking for, will check all other your design lessons
Dam I'm glad that I watched this, some weeks ago I CADed an adapter for a cooling fan to a 3'' duct for a painting booth and did everything manually, I didn't know loft and shell tools could be used that way
Your F1 related wardrobe is almost as impressive as your tutorials :)
Thanks for another great video !
I fell asleep watching this
So it auto played 7 more of your videos
So came back to watch it again lol
Your welcome 😂
Thank for the tip about adding vertices! I always got stuck there...
great content! ill be using this to duct oem fresh air on a 71 coronet into a 78 corvette dual snorkel air cleaner for a really clean look
The nice thing about parametric design is that different programs have similar workflows. I am sure I use the program I use, Freecad, to design these parts instead.
I want to get into 3D printing. And this is one of the things I wanted to do. I'd use this stuff to help flow air to the Nitro engines to help cool them better.
This is awesome! Man, i am learning how to design (and made some successful models) are going to enjoy this. I want to make a better duct than the one i designed and that i cant support in the way i made it. But with this, now i can! I was using tinkercad, great for a lot of things but not for complex models
Awesome! more CAD videos! 🤩
Love this man!
Definitely learned some extra functionality of lofts and the pull face tool in this one
Also how the heck am I not subscribed yet...was*..was I not subscribed yet Keepo
Wow! I learned a lot in this segment. The flow of information was fast, but OK. I will have to work thru that video a bit slower to try the concepts.
Thx for keep this down to earth interesting, while challenging.
Great video Michael.
Very cool. Going to have to play with this!
I converted to OnShape at the start of the year after my Solidworks licence expired. I've been very happy with it and running it on an old gaming laptop doesn't slow it down compared to Solidworks.
Thank you sir, great channel…
Thank you, that's just what I wanted, free tool to make ducts.
Now that is cool.
Now I can print matching feet for my fan.
Your videos have actually got me to start making my own intake for my om617 swapped 4runner. I picked up a ender 3 pro for 100 bucks on market place and my first print is going right now after 3 errors.
Awesome! I hope it turns out well.
@@TeachingTech I'll post some photos. Thank you for the content. Really means a lot.
Great tutorial
love the hoodie and the car team
I used Solid Works, " when I worked" and the similarity with this program is apparent. 👍✌🥃
Amazing tutorial, far superior than tinkercad.
Love your vids dude👌
Thanks a lot, great videos!!!!
Thank you so much for these videos. I've been wanting to learn this for awhile but didn't know where to start. Are you going to keep making these videos weekly?
Awesome work!
I've used Fusion for so long now! But, I'd like to try something new. Onshape really looks like a capable program. Thank you for these intros.
Thank you so much!!
Very inspiring!!
Really useful, thanks! 👍
I don't use loft enough... good reminder dude thanks
