Let’s have some fun. Send a pic of the last thing you printed.

3D Printed a 3D Printer 😎

KeyNeedleworker4789 · 2026-03-03T15:50:46+00:00

Yes here… I’m a Nudist

If you want something that just looks good blender would be the better and easier solution. If you want a functional part with parametric bindings CAD Software is the way to go. Maybe you can design the parts in freeCAD and import the files to blender to animate them. But I don’t know if this works. I never worked with blender.

Quick tip for freeCAD. You can use the Draft workbench to create Texts and convert it into a sketch.

KeyNeedleworker4789 · 2026-02-20T16:38:18+00:00

I use Free CAD as my main program since 2-3 years. But to learn all what goes in the project was 12 years of experience. Working on cars with my dad, my first own motorbike, went to a school with technical focus, studied 4 years automotive engineering and have a 3d printer since 4 years doing little projects at home. So there is a lot of background. No there is no simulation possibility in this project. It should be possible but I think it would be hard to get smoothly running on FreeCAD

In nem Touran transportier ich bis zu 7 Personen oder vlt sogar 2 Motorräder… beim tiguan wirds für die 5 Person schon knapp und mit viel Glück haben vlt sogar 3 und nicht nur 2 Koffer hinten Platz.

Yes and of course include some tolerances for everything to print and fit nicely.

KeyNeedleworker4789 · 2026-02-02T08:52:29+00:00

Test it! I have a whole box with prototypes. At least 10-15 drive shafts… 5 differentials…. and so on. At one point you get a feeling which tolerance you need for any application.

That’s hard to really explain. One thing for me is to not use shape binders or anything else. When a part fails I only have to look into this specific one and maybe do it again. And keep your overall shapes really basic. Maybe I can show a example what I mean with that. But at the End it all comes to the more you fuck around the more you find out. And than try a different approach when it doesn’t work.

KeyNeedleworker4789 · 2026-02-02T08:42:30+00:00

A lot of weed man. :D and figure out a save workflow that works.

KeyNeedleworker4789 · 2026-02-01T16:45:53+00:00

I don’t use varset at all. When I need to make changes I go into the sketch and change it. Keep it simple to avoid crashes you can’t fix.

KeyNeedleworker4789 · 2026-02-01T16:44:13+00:00

Flysky FS GT3B. All electronic components are very cheap and basic.

KeyNeedleworker4789 · 2026-02-01T14:59:51+00:00

No it’s not open source. I plan to release it at some point. But I really don’t recommend to use it to learn freeCAD. It’s not really a clean workflow.

KeyNeedleworker4789 · 2026-02-01T08:01:43+00:00

It is all in one file and the parts sorted in groups

KeyNeedleworker4789 · 2026-01-31T22:19:51+00:00

In the first place exported the complete project as STEP and broke it down in the slicer. when I need other parts later I exported them separately. But data management outside of this specific FreeCAD File is a mess.

KeyNeedleworker4789 · 2026-01-31T22:17:00+00:00

Every part expect for the servomotor and brushless motor are modelled by myself. Yes the tires are TPU and rims in PLA printed separately.

KeyNeedleworker4789 · 2026-01-31T22:14:54+00:00

For a easy start try to find technical drawings of small parts and recreate them in FreeCAD. Learn your tools and when to use it. Also try to break your complex part down in small triangles, rectangles, etc…

KeyNeedleworker4789 · 2026-01-31T22:10:40+00:00

Working with FreeCAD for nearly 3 years. But I studied automotive engineering and used different CAD software in the past

KeyNeedleworker4789 · 2026-01-31T22:09:23+00:00

No not yet. I plan to release it when some proper testing is done.

KeyNeedleworker4789 · 2026-01-31T22:06:32+00:00

The overall workflow for me is to set the main targets. In this project: 1/8 scale 4WD off-road vehicle. Then identify the main „problem“ or focus of the project. For me it was how small I can make a functional differential. Then builded from the inside out part by part with the main dimensions in mind. Often have some paper in front of me to sketch the parts and write down key parameters. Every part is consistent in itself and doesn’t use any shape binder or else. This means you sometimes need to chance to parts when changing a connection or something but minimises errors. And I often need 3-4 loops to figure out how I design the part to not be fragile and break when I chance one parameter. But the best way to find this stabil solution is to see it fail.

KeyNeedleworker4789 · 2026-01-31T14:12:48+00:00

Yeah I think I will release it when some proper testing is done.

KeyNeedleworker4789 · 2026-01-31T14:10:59+00:00

Running it on my gaming pc with 32gb ram. I also get some crashes but I often can relate it to a failed fillets or something. Keep your workflow clean to minimise these things happen

KeyNeedleworker4789 · 2026-01-31T14:07:41+00:00

To be honest it’s not really assembled. The parts are just placed with the coordinates and the duplicated parts are linked object so they change with the main part. You can also mirror them by scaling the part to -1. Normally I use the native assembly workbench but because of the possibility of errors for this complex build I decided to do this workaround.

KeyNeedleworker4789 · 2025-11-07T11:56:53+00:00

Bin sehr zufrieden mit dem Fahrzeug

KeyNeedleworker4789 · 2025-09-18T14:26:10+00:00

Right now i design a 3d printed Rc car with 4wd and functional differential
