NEMA 17 Homing Flag And Endstop Plate
A 5 mm plate that sits between a NEMA 17 stepper (31 mm M3 bolt square, 22 mm pilot) and whatever it's mounted to. It has an arm with slotted holes so you can slide a microswitch or optical endstop in or out to line it up. It prints with a flag collar for the 5 mm shaft (M3 set screw) attached by a snap-off tab, so a rotary joint or turntable can home to a repeatable position.
