3 1/2" Steel Balls Fidget Spinner

This spinner uses a 608 bearing in the middle, and 1/2" steel ball as weights.


Steal-Balls I've used can be found [here](https://www.amazon.com/gp/product/B004PX9KO0/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1)

I recommend [VXB](http://vxb.com) for bearings.

You can use your preferred cap for the bearings, there are so [many](http://www.thingiverse.com/search?q=spinner+cap&sa=) versions out there.
