Fidget Spinner

Fidget Spinners can be cheap, i wanted to design my own simply, because I could. It was a fun process.
The caps provided the largest problem, finding the best dimensions for the grip,tolerance for 608 bearing and clearance of the bearing and underside of the cap.

Testing the dimensional accuracy and reliability of my printer regarding dimensions was easy enough, i took some advice from 3DPrintingNerd from youtube to have a tolerance of 0.05. This tolerance worked out great for me :)
