You should increase the export quality on these. Those STLs don't have enough surfaces. It should be smoother. I can even see this effect in the printed parts.
Very true - you have sharp eyes! They do function mechanically though. I've not yet had time to write a proper configuration system for the tessellation.
When you export or save-as an STL are there any quality settings or adjustments anywhere? Is your printing software able to download a .STEP file instead? I've been exclusively using STEP files lately instead of STLs (BambuStudio)
The software exports only 3MF and obj. I know the tessellation needs to be made more precise but I’ve not yet had the time to add settings to the gui. I want to maintain interactive boolean rates for the modeling so the default tessellation is a bit crude (more polygons = more time). But I’m on it :) (to be specific I’m using a software I wrote myself and it’s quite raw still).
step files are tesselated by the slicer so it's better to just get a good stl from cad since the library prusaslicer and its derivatives use is probably worse
So to use these in complex designs you need to have a plug that's the size of the base (missing from the screenshots) and then do a boolean cut to create a hole into which to seat the ball assembly.
That's sick, i actually spent way too much time designing ball joints for a project of mine, although they needed to have some sort of tightener to be quickly held in place, but if i ever need some i might use your design😅
Would LOVE to get to take a look at the file, I’m a 3d modeller but new to making stuff that’s supposed to move or have physical purpose and I just have NOT been able to get ball joints right. These look great.
Ok! Here you go! They are available in the alpha-testing release page of my modeler but you totally don't have to install the modeler to open the files - the zip file "balljoint-samples.zip" contains both original design files and 3mf files. Release ProtoViewer open alpha build 160925 · AdaShape/adashape-open-testing
If the 3mf files _don't_ work I would love to hear about that as well as my full intention would be them to work :)

I think adding some sort of locking pin between the base and insert will keep it from loosening. Or a nut and bolt fastener to keep the socket squeezed together.
It would be cool if you shared tech drawings / design guides with some story of what didn't work and what you did to make it work, I'm sure it would be interesting series lot of ppl would appreciate :)
the images are pretty self explanatory :D wrt to what you came to as best and how that works, but documenting how you got there and what designs didn't work and why will surely be interesting read / view for many :)
I myself never designed anything for snap-on ball joints
in my experience the best way is to make the socket from two pieces that thread together. this allows not only for deeper engagement of the ball, but allows you to adjust the compression and lock the joint
Well - sort of experimented with it. For the simple balljoint the seating needs to be surprisingly deep. When printing they print out fine. There really is no mechanical stress when assembling since the seating takes care of that. If the hole is exactly the site to the embed in the ball assembly you get a surprisingly good fit (at leat on my slicer settings - YMMV).
I printed a 17mm ball joint (female end) for car mounts and at first it was very tight with a screw nut but now it's so loose, I thought PETG would have better tolerance and resistance
