Developed by: armpit A 3D-printed modular quick-release mount ecosystem for NEMA23 motors, featuring:
  • 4-degree precision quick-adjustable rotation
  • Motor can be quickly removed for storage or use in another base
  • Stress tested to 50 ft-lb without grip compromise (PLA, 6 walls, 10% infill)

The iHSV57 ring prints as one piece but snaps into two halves after removal from the printer. Clasp each half around the motor to assemble.
iHSV57 motors smaller than 180w require modifications to the ring design.
