Simple fidget spinner

I decided to make a fidget spinner that did not use more than one bearing (an easy accomplishment). Without the other three bearings you have to print dense to make up for the loss of weight and it still works great. I recommend using caps on the bearing so it is easier to grab, This is the one I used http://www.thingiverse.com/thing:2083000/#files
I printed the 608 cap at 96% and it fit perfectly.
