Ballhead in its abstract form. It requires m3 and m5 screws. Including STEP files so you can build something different on top of this and modify the holes if you wish to.

I used %20 infill with a little flexible no-brand PETG, I'd assume it should work fine with better quality PETGs, PLA+ (won't be as brittle as PLA) or ABS.

It will require support or brim. If you have good cooling you might get away with brim.

If you happen to use the M5 screw for holding ball in place, please take a look at the knob I made for M5 nuts and bolts as well: https://www.myminifactory.com/object/3d-print-150031

Sample in the demo uses this knob and it's printed at low resolution, high speed settings with Prusa Mini.

Update #3: Added the setup I used for my Prusa Mini Octoprint setup. With mesh head it's not so abstract anymore.

 Update #4 (experimental): Very heavy duty version based on meshed head added. I printed this in PLA+ and stripped the threads inside the ball-head (meaning the plastic couldn't take the stress), therefore added two new models to optionally support this scenario. M8 Nut coupler (needs metal M8 nut) and sheath to cover the coupler so nut won't come out. It needs glue to stay in place, super strong.
