Stator winding jig

A winding jig for a drone-motor maker, with a magnet locked inside the print.

Two blue printed jig parts: a flat plate with a raised rib and a half-round holder
The job
A drone-motor maker needed jigs to hold stators while they are wound, through a prototyping phase where the design changes every few weeks.
What I did
The print pauses partway so a magnet can be set into a pocket, then the printer closes it in: no glue, and the magnet cannot fall out. The first print failed on a design detail, so I worked through the fix with their designer and reprinted.
How it turned out
Part of an ongoing prototype run. Later versions move to stronger materials as the design settles.
