Summary

This is a proof of concept to print a ball tip (or ball and socket) in one piece.

The default size has clearance of 0.2 mm. It rolls very well for me. Quite a fidget thing.

I have success to print it at 50% size by my Prusa MK3.

IMPORTANT: print it upside down (ball touch the print bed), activate SUPPORT FROM PRINT BED ONLY in your slicer.

Please post your creation if you make applications with it.

Post-Printing

IMPORTANT: there are two tiny bridges connecting the ball to the socket for temporary fixation. Sand the support scar, then cut the bridges to free the ball.
