Nickel Fidget Spinner

##### Nickel Spinner!

I wanted to continue learning Fusion 360, so I made a fidget spinner. Didn't want to use 2+ bearings per spinner however, so I changed it to use 3 nickles as the counter weights.

----
##### Design

The nickels are locked in with a threaded lock ring. It can be a bit tricky to get threaded, but it does thread, even if you have to snap it in first a bit. The thumb stud is a screw design because I didn't want to glue anything.

##### Included

Included is a single spinner (uses 1 bearing and one stack of nickels), and a dual (uses 1 bearing and two stacks of nickels).
