Fidget Hand Spinner

I used the diameter of a 608 skate board bearing to get the dimensions of the inner circle. That way a 608 bearing will slide into the inner circle for the spinner to work. I added three other circles on the outside of the spinner base for you. This way you can add objects that weight the same to keep the spinner rotating for a long tome. When we tested it, it was spinning for a max of 5 minutes and 49 seconds.
