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.
