Nema 42mm Servo plate

thingiverse

I was creating custom brackets for my latest printer project when I hit a roadblock finding a precise mount for a standard 42mm servo motor. The issue lay in its unusual 23mm central opening, which provided just enough clearance to accommodate the servo's 22mm center boss, but retained the same outer dimensions and bolt pattern as the original unit. To offer some flexibility, I also designed a version with a 22mm central hole, which should fit snugly on the motor, albeit perhaps a bit too tightly around the center boss.
