WCChapin | As the Worm Turns…The “Annealid” – Testing a 3D Printed Gear Reduction for a Case Annealer
William C Chapin
A few weeks ago I modified a servo for continuous rotation by removing the feedback potentiometer and rotation stop, and also wired the motor directly.
While exploring gear reduction ideas on Thingiverse, I stumbled upon a perfect solution by “dasaki” – a servo driven 30:1 worm drive. I modified the design slightly to use a rotating 3/16″ music wire output shaft and printed bushings rather than the specified ball bearings.
The dimensions of the gear drive matched a standard Futaba mounting tray perfectly and everything screwed together easily.
