Category: Mechanical Toys Summary

Bring Your Own Balls Fidget Spinners come in three sizes, 45, 55, and 65mm radius. Each spinner requires 40 6mm air soft ammo for the bearings. The bearings are from one of my other things https://www.prusaprinters.org/prints/45739-byob-parametric-bearing with the outer races integrated into the body.

Bearing assembly is described on the page with the bearings and I recommend a little glue when fitting the inner races together to help prevent them coming apart if you drop your spinner.

Files are included that have all the parts for a spinner or you can print a body and 4 bearing tops and 4 bearing bottoms.

I needed support for the bodies to prevent perimeter bridging on the inside radius curves because of the fillets.
