I wanted to make my small bit ratchets easier to spin, so I designed a spinner to be added directly to the bits.
I mostly aimed it at the longer E type bits, but it should work with short bits too.
Back of the spinner has a cutout for the drive mechanism, I tested it with the Wera and Prestacycle ratchets. The fit is pretty tight, I used a vise to press it on. After installing the spinner for the first time it can be moved and removed by hand. You may scale the model if you prefer a looser fit.

Inspired by @DaveRome_169024's love for ratchet spinners.

Printed with 4 perimeters in PLA, 3 is probably plenty though.
0.2mm layer height
