Printed 4, some washers came out better than others (I suspect that was the fillament). Other questions. 1. Why the hole in the top of the ball cup? Also I get better spin if I loosen the nut but more movement. Too much of a gap and the spacers/balls come out. Any tips? Should the screw be spinning when the top spins or no? Thanks!
