Filawinder drive gear-no screw

thingiverse

This is a remodel of the original drive gear with the following changes: 1. deleted cylindrical void in center of gear face 2. deleted the screw hole and nut slot 3. added flat to index to motor. My opinion is that the screw is not needed, the herringbone thread pattern will keep the gear from wandering and the flat allows for a significant increase in strength. I have also included some adapter rings for spools with a 59mm ID.
