8 mm Rod Split-Clamp Endstop Trip Collar
A split collar that clamps anywhere on 8 mm smooth rod with one M3 screw and a captured nut. Its 2.4 mm trip blade breaks the beam of a slotted optical endstop, and the 6 mm arm face presses a microswitch lever. It gives you adjustable travel limits on rod-guided carriages and arm axes that have no motor shaft to put a homing flag on. The collar is 22 mm OD x 10 mm tall with an 8.3 mm bore, and the part is 62 mm long overall.
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.
