A Tri Spinner inspired by Atoms and their electrons. It uses 1/2" ball bearings as weights. Central bearing is standard skate bearing.
Ball bearings and skate bearing needs to be press fitted into place.
When printing the spinner caps, make sure you print them with either more infill or 3 walls to ensure rigidity.
If you do not want to go through the trouble of press fitting or just want to support me, I sell it on my Etsy: https://www.etsy.com/shop/JPDesigns3D?ref=hdr_shop_menu
