Standard Actuator mounting base: PitClamp Mini

Standard PCB mount: PCB Enclosure

PitClamp Mini v1.1

| | | —- | —- |

Developed by: armpit

3d printed modular quick-release adjustable and removable mount ecosystem for 57AIM, 42AIM, iHSV57 NEMA23 motors.

• 4 degree precision quick-adjustable rotation
• Motor can be quickly removed from mount for storage or use in another base

Stress tested to 50 ft-lb without grip being compromised. (PLA 6 walls 10% infill)

Supported motors:

| 57AIM (30/15/10) | 47AIM (30/15/10) | iHSV57¹ (180w²) | | —- | —- | —- | | | | | | | |

¹:The iHSV57 ring is two parts but snaps into two pieces after removing from printer. Clasp each half around the motor to assemble.
²: Smaller than 180w iHSV57 will require modifications to that ring.
