Multiple Mechanism Auto-Rewind alternate rack
thingiverse
These are alternate racks for the Multiple Mechanism Auto-Rewind spool holder. The 21-tooth should work with the regular holder, the longer options I use with the wall mounted version from gcode22 [here](https://www.thingiverse.com/thing:3953625). These feature a straight gear profile, which is the correct involute for a rack. This resolved the issue I was seeing where the rack could get stuck in the fully up position due to the gears not quite meshing right. ToT has a fun [video](https://www.youtube.com/watch?v=qVN2jrn4Kuo&t) on this subject if you are interested.
