Update - 4/25/17: I shortened the length of the screws by 1 mm. This left me with the most snug fit on the bearing without over-torqueing the screw and possibly breaking it.
I decided to do my own take on a fidget spinner. I just started making simple shapes in fusion 360, and after getting a rough idea of the layout and some fine tuning we have this spinner. This uses standard 608zz bearings for the spinner and weights.
