Toothed fidget spinner

The wife brought home a spinner she bought from a friend for our son. Looked at it and said that I could make one. I added 48 pitch teeth to the OD for a little grip. Designed for 7/16" hex nut, but 3/8" flanged nuts work as well. It's as thick as the nuts so not great for little hands. Haven't created the center pads. If you make your own they'll need to be taller than most to deal with the thicker spinner. Feel free to alter.
