A simple multicoloured fidget bearing that prints in one - I've included the Flashforge AD5X emf so you shouldn't have any problems with the tolerances. It's interesting to see how (badly) the printer creates the spheres but the bearing does work and spins well. It's designed to be fitted on a keyring, its about 1" inch diameter.

I've included the Alibre file and a step file so you can see the gaps (tolerances) I've used as the stl facets them obviously
