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)

Supported Motors

57AIM (30/15/10)	42AIM (30/15/10)	iHSV57 (180w)

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.

Print Settings

Setting	Value
Walls	6
Infill type	Cross Hatch or Gyroid
Infill percentage	10%
Supports	Tree Supports, 5° threshold angle
Seam	Nearest (or your preference)
Filament estimate	~150g
