My wife loved the original but felt it didn't spin much and she wanted a 3 bearing so I remade the design and kept it as small as I could and managed to fit 3 bearings into it. The holes should be the perfect size for the bearings, but it may take a bit of either sandings or filing of the holes so it will fit(depends on your printer it seems). I did not design or mess with the caps those are just ones that me and my wife prefer. I did include the file but I did not create them I did mark this as a remix of the original so go check that out.
