Top whorl fidget spinner adaptor

thingiverse

This is a straightforward adapter that turns fidget spinners into top whorl drop spindles. It's designed as a direct replacement for the commonly used 22mm bearings in fidget spinners. Simply remove the bearing and push the adaptor in, then insert a 1/4 dowel (a length of 10-12 inches works well). Next, screw a cup hook to the end of the dowel and you're done. If you want to ensure your spindle stays still, use some CA glue.
