I got my 3d printer mostly as a tool to help with other hobbies, and I had no CAD experience starting off. This is helping so much and I have been able to solve issues and print functional parts.
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.
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...
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)
Michael, I've been fighting FreeCAD for months. (I'm used to AutoCAD), and OnShape is my new modeler for sure. Thank you for all the time it took to make these.
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
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
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.
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.
@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
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!
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!!
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.
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.
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.
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.
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.
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.
Dude, you blew my mind a couple times with this tutorial. Thanks for the education! I'm excited to try these moves out on my new OnShape account. Cheers from Wisconsin, USA! 🍻
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
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 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.
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!
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
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.
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.
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.
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!
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!
What a coincidence. Just recently I got the idea to add some pc fans to a display cabinet to keep dust out. I was thinking of adding a duct to put a magnetic screen mesh and I was just gonna jump into blender as usual, but in the back of my mind I was thinking I should try to do it in cad. Guess I have the perfect excuse to do it in cad now.
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.
Ahhh Yes a Duct tutorial, everytime i need to a new duct i need to ask someone to help out. Thank you TT I use Fusion360 but nothing prevents the use of different programs
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
This is great! I've have been using onshape since you recommended it in an older video and it has served me incredibly well. I especially love that it's free and pretty powerful. Web browser-based is cool too!
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
This is just the video I needed to adapt a 5015 fan for my weird DeltaMaker 2 that has like no community mods. It doesn't come with a part cooling fan, or a heat bed, costs a stupid amount of money, but I won it for free at a maker fair, so I might as well use it and try to upgrade it
Making molds is fairly simple. Make your part, then make a large box that covers them, then use the Boolean tool to subtract your part from the box. You now have a box with an empty volume in the shape of your part. However, there's more to making a mold that isn't so much about CAD as it is about making molds. Check out Robert Tolone whose channel is full of examples of making molds with some great insights into the process. It takes some practice, but you can do it in your garage with some easily available tools.
Wow. This is one of the #1 things I have always wanted to learn to do in modeling and was 100% concerned it'd be too hard. This is a masterclass in good lesson planning. I can't wait to make an adapter for my bench top planer now!
this is one of the greatest tutorials I have ever seen on youtube, thank you this is GOD TIER

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.

Perfect Tutorial whilst also showing what you can use it for!
Keep it up man!
I've been trying to do this sort of thing in Fusion for a while now and this helped me through figuring it out!
I can recommend the Create Part Studio in Context feature of the assembly view. It allows you to isolate concerns in a clean way.
Your F1 related wardrobe is almost as impressive as your tutorials :)
Woooooooow I needed that tutorial so much !! Exactly what I wanted. Cheers man
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.
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.
