Derivatives for servoholderV1, PistonanticlockV1 and PistonbaseantiV1.stl for using a stepper motor instead of a servo.
Changed the pitch of the screw, as it was too steep for the stepper.
Video of bicep (and hand) in action.
Print stepperholder and StepperPistonbase at normal infill. I use 20%. Print stepperdrive at 100% infill.
No support needed.
