This fits a 12mm or 19mm socket to drive the winder.  The motor should be low/medium speed (screwdriver) since the gearing already gets the spool spinning fast.

Print this using high-strength settings, extra walls and high infill for strength.   Glue in place over the 9mm hex nub on the winder, being careful not to glue it to the frame.
