Spinners with Balls (and a Top Converter)

An assortment of four spinners that use steel shot or ball bearings instead of the typical bearings in each arm. I've also included the STL for spacers to allow you to properly countersink the standard ball bearings into the designs as well as an adapter that let's you turn almost any spinner into a top.

A how-to video for designing your own fidget spinners as well as a quick test of the top adapter is available at: https://youtu.be/ITrUT2tqut4
