Carriage Clevis Output Tower
This clevis output is part of the 'NEMA17 Leadscrew Push-Pull Actuator' kit. Its 40 x 36 x 5 mm base bolts to the carriage top with four M3x10 screws. They go through 3.4 mm holes on the 20 x 20 mm MGN12H pattern, with 6.5 mm counterbores. Two gusseted ears stand 35 mm tall with an 8.4 mm gap and hold an M3x20 pin and a nyloc 28 mm up, across the actuator axis. The ears are 12 mm wide so that a hex key can reach all four screws.
NEMA17 Leadscrew Motor End Block
Motor-end block for a DIY linear actuator. It holds a NEMA 17 stepper on the 31 mm M3 bolt pattern and 22 mm pilot, with two 8 mm guide rods 60 mm apart, each locked by an M3 heat-set grub screw. A flanged foot with M5 holes bolts it to 2020 extrusion or a baseplate, and gussets carry the load.
NEMA 17 Twin 8 mm Rod Motor End Block
This motor-end block for a DIY linear axis mounts a NEMA 17 stepper on its 31 mm M3 pattern, with a 22.4 mm pilot/coupler clearance bore. It clamps two 8 mm guide rods parallel to the shaft on 70 mm centres, and each rod socket has a split pinch clamp tightened by a captive-nut M3 bolt. A rear tab carries two M5 holes 40 mm apart for bolting to 2020 extrusion or a base plate. The part is 90 x 68 x 30 mm and prints flat with no supports.
