3/4'' Stainless Steel Nut Fidget Spinner

thingiverse

This spinner's performance is impressive, thanks to its rotating mass. The better your bearings are, the longer it will spin. I purchased these 3/4-inch stainless steel nuts from Ace Hardware. The screw for the end caps should be a 4x5/8 inch fastener or any other size that fits well. My high point balancer picture is an essential part of the spinner process. Good balance leads to a very stable spin and longer spin times. I used hot glue to balance this spinner, and so far it's working great!
