Penny Weighted Spinner

thingiverse

This is my first attempt at crafting a fidget spinner. To assemble it, you'll need: 1x central core 12x precision bearings 2x outer caps 1x main body The central core is placed in the center hole, and the bearings are fitted between the core and the body. The outer caps fit inside the central core, closing the mechanism and providing a secure grip for your thumb and finger. You should insert three American pennies into the holes on the wings to add weight. Edited as of July 6, 2017: I modified the central core to make it thicker, which reduces slack in the mechanism. I recommend using 12 bearings instead of eight. I also adjusted the outer caps by reducing their height in the bearing housing and adding a peg to one cap so they interconnect. Edit #2: Interlocking end plates
