Ducts and adaptors using Onshape loft and shell - 3D design for 3D printing pt3

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.

[@jester65jn]

love the hoodie and the car team

[@jameslmorehead]

Very well explained. This makes me appreciate Solidworks even more. Adding in the plane to sketch the output is as easy as setting an angle from another plane or surface and a distance from a line which is parallel to the new plane. Sounds complicated, but take less than 30 seconds to execute. This seems a bit more complicated as the software is not as intelligent. I might look into the flow simulation side of the software as my solidworks license does not include any simulation modules. I have a few fan designs for MajorHardware's Noctua design contest that I would really like to optimize before submitting them. I think I can beat the reigning champ with much less volume of hardware.

[@austinclark3495]

and this software is FREE?!

[@NovaSilisko]

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...

[@LightSpeedIII]

@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

[@nathan22211]

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

[@aaronchamberlain4698]

May be one of the only non-positive reviews. In the future, don't be afraid to be slightly more verbose and go step-by-step, or assert critical areas. I feel like I had a really good grasp on things from your last video and then came into this one just lost. You start your sketching with the sketch already complete on the back of the fan. I was honestly confused at how to fully constrain that sketch and it took an hour. Kinda killed the flow. EDIT: Finally finished this design and it likely took me 6-7 hours. Particularly had a weird bug where the first sketch did not create a new part and instead is part of the imported part. You also mention at 9:27 to clean up the extra vertex, but mine was at a different location. Would have been helpful to show what the "Connections" checkbox does to troubleshoot.

[@DWIT3D]

THIS has now turned me on to Onshape. Thanks so much Michael... excellent tutorial!

[@railgap]

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.

[@sikhswim]

this is one of the greatest tutorials I have ever seen on youtube, thank you this is GOD TIER

[@pkucmus]

I can recommend the Create Part Studio in Context feature of the assembly view. It allows you to isolate concerns in a clean way.

[@dr_gotheem3899]

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.

[@FireN2k9]

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.

[@reverse_engineered]

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.

[@3dservicesllc]

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)

[@PiefacePete46]

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!

[@woodcat7180]

I like the new series, but wish you would cover all the steps in one video without the need to jump to older video. This might be fine for more advanced users who are familiar with other cad sw, but not for beginners like me. I realize you just want to build up on what we learnt last time, but even though the concepts are the same, it's hard to see how you got there (@4:53). I don't think this would add much length to the video.

[@gdjsky01]

Yes. I agree. This video just went too fast. I realize that he may be limited in length, but the part the duct fitted on (the fan bracket) needed step-by-step as well. It's a long ways from two rectangles of the tool holder to that mount

[@15fireguy]

I generally love your videos. Except this one. I use F360, not an expert but I get by, so i have a decent working knowledge of parametric design but….. I feel like you went from “here is how you turn on a computer” to “now let’s use python to program my coffee pot to wake me up in the morning”. I was legitimately so lost before the halfway point of the video that I just closed the video and will wait for this series to be over. (I voted yes to wanting this series btw)

[@oojagapivy]

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.

[@ruuman4]

These instructions could've been a bit more detailed. I've been struggling to make this work, and even though I've had some success, I hit a roadblock here to my progress. This IMO really should've had a whole lesson just on modeling around objects. I'm gonna check out another tutorial and maybe swing back here later. Still love Onshape, probably gonna stick with it instead of Fusion 360. Thank you!

[@TeachingTech]

Hopefully you can find what you need. To keep the video concise I try to build on the previous videos. Sometimes people come in and wan to follow just one video to make a whole specific part, but these videos assume prior knowledge from earlier in the series. Not ideal but I figure it's better than each video being 30-60 minutes.

[@ruuman4]

This lesson is exactly what I need but... I guess I need more practice making constrained sketches and complex geometry. I'll figure it out and come back and watch the rest and will leave tips that will hopefully help other please. I love the channel!@@TeachingTech

[@ToniCorvera]

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.

[@solish3458]

You might have used the loft function on the sketch and extrude, use it on sketch and sketch instead, might help!

[@ToniCorvera]

@@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.

[@ianpimlott2588]

I use on shape and found your first video very basic and was easy to follow but your second was straight into ducts and at the beginning you skipped over a lot and even though I understood most of it and could muddle my way through it would have been helpful to do it as a full step by step for the first three or four videos instead of " look at this video or that video" so people can follow along and try it out making it a more fun and smoother experience

[@ajhartmanaero]

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!

[@antiwaffles]

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.

[@DJKingArthur]

Congratulations you just resumed mechanical engineering curse in a video 🤣🔥 Im staring to feel like I lost a lot of time in my BA on Mech Engineering

[@smolzillamakes]

I've been trying to do this sort of thing in Fusion for a while now and this helped me through figuring it out!

[@xjonx1]

OK. I'm lost already. I have a box that's extruded next to another box. I want the boxes on top of each other. The way to move an object IS NOT obvious. Where is the move object tool or the align tool?😡

[@xjonx1]

I "figured it out" and it is TOTALLY unintuitive. You have to click on "transform" even though you are not transforming anything, just moving. You then have to select a point ON THE OTHER OBJECT. You then tell it by distance. Then choose a random distance, then change the distance different amounts until you get it lined up. Then click the green check to stop moving. I'll stick with this series but it and OnShape are "On-The-Bubble". As a complete beginner, TinkerCad's click and drag without the weird and randomly named tools is superior.

[@jona_ej2330]

Let's see if i learn enough to print my own aero parts for my Honda civic... Can we see more of making molds? Thanks SO much for your videos!

[@reverse_engineered]

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.

[@jona_ej2330]

Pro tip: u can actually use an STL, but not edit it as u might think, the easiest way to use it is as a reference, so u can copy the shape and the hole position

This is nice and all, but to get this "free" version, they are "requiring" too much PERSONAL info!

Especially on a website that I'm not familiar with.

[@tomich6430]

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.

Doubly so when their cheapest full plan is $1,500 a seat and basically the whole planet is in a recession.

[@superdupergrover9857]

Is there any hobby level printing of automotive electrical connectors? I have heard of Nissan partnering with a company to make some for older tuner cars. Electrical connectors can get really pricey (60+ usd) when they no longer have high production volumes. And all the really hard to print stuff is mostly standardized, like the metal electrical pins and the weather seals. In fact, the sizes and shapes are also mostly standard but there are thousands of combinations of size, shape, pin count, pin configuration and bumps/fins. The latter two is a big problem because they are designed to keep you from put the wrong plug in somewhere. Sorry for the rant, but I sell car parts and I hate telling my customers that "The connector will cost $60-80 and will arrive two days from now." I know I sound like a boomer, but in this day and age, I shouldn't have to say that. We have the technology and the resources to do better than that.

[@dennisfahey2379]

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!

[@larrydeem3071]

I am designing ducts to replace fog lights in my car and connect to brake cooling hoses. I am lofting between rectangular opening and round outlet. My trouble is I want to add flanges that would intersect the duct body on the lofted shape. In other words between the two ends of the loft. I can make a flange that intersect one face of the loft but I can't figure out a way to make the flange wrap around the loft. The loft is tapered and I want the flange to smoothly transition into the loft. Wrap tool only works on one face, Boolean command fails, use command works but I can't merge the flange to lofted body in order to create a fillet between flange and lofted shape. Any advice?
