A simple fidget ball using MX style switches and keycaps to make a satisfying clicky little toy.  This is directly inspired by a photo of a similar fidget ball sent to me by my wife sold by Strudel3D.  I take no credit for the idea, but the design is my own, and is quite simple.

Ball can be printed in two ideal positions.

1. Vertical with supports - Gives the best surface finish, with some minor issues around the bottom facing socket, but lots of support removal required.
2. Rotated 45 degrees - Minimal supports needed, but does deface one of the balls surfaces.

I have included both, along with a variant with a slightly bigger opening for keycaps, so you may choose what fits your preference best.

MX Switches clip into the sockets on each face, and the keycaps then attach on top.
