Gripper Motor Frame Plate
The 150 x 110 x 6 mm base plate for the 'NEMA17 Rack-and-Pinion Parallel Gripper' kit. A NEMA 17 stepper bolts to the back using four M3 holes on the 31 mm square, and its 22 mm pilot boss passes through a 22.4 mm hole. Two rod end blocks attach at x ±64 with M3 screws, and the 2020 wrist bracket attaches through four M3 holes at (±25, 38/50). Through-pockets bring the weight down to about 58 cm³, with an 8 mm stiffening rim left around the edge.
Rack And Pinion Linear Drive Block
A print-in-place module-2 rack and pinion linear drive: a 150 mm toothed rack slides through a 60 x 54 mm housing while a 16-tooth pinion (32 mm pitch dia, 100 mm of travel per turn) turns on a 5.3 mm bore for any 5 mm motor or gearmotor shaft, locked with an M3 screw into a captured M3 nut in the top collar. The housing bolts down through four M4 clearance holes and the rack carries two pairs of M3 heat-set bores on top for your carriage — a cheap linear actuator for gate, hoist, feeder and camera-slider builds where a leadscrew is too slow.
