Fidget Spinner Phone Case

thingiverse

iPhone 6 / 6S case with a fidget spinner knob on the back. Works with a standard bearing that attaches to the case with a plug, and then a wheel snaps onto the bearing. The wheel has a slot for a 1/8" bungee to go through that you can put your finger in to easily hold your phone - knot bungee from inside before putting around bearing. A layer of smooth paper can help reduce friction between the case and the wheel. Shimming the plug and bearing will help if the fit is loose.
