Made quickly (and sloppily) to keep the two extra heads that came with my Synoshi scrubber. I know myself well enough that if I don't have something to keep them together in a drawer they will quickly go missing.

Printed @0.2 mm LH, on it's side for strength.

Thingiverse is too hard to upload on. I don't know if it's worth uploading and maintaining things here anymore.

All the best.
