Smooth Operator TRI Fidget Spinner Pennies

I decided to give it a go and create my own. My thumbcaps are great because they sit on the inner bearing race and are the whole diameter of the bearing to help protect a little better from debris getting into bearing. Thanks Joel!

If you print, please provide pics and link back to original. TY and happy printing!
This design uses 1 608 bearing and 15 pennies.
