X Arm Root Motor Block
A root block for a robot arm. A NEMA 17 stepper bolts to the underside of the 6 mm plate on its 31 mm square M3 pattern, with the shaft coming up through a 22.4 mm opening for the motor's centring boss. Two slit clamp sockets hold the arm's 8 mm rods 40 mm apart. Overall size is about 96 x 56 x 28 mm, and each rod clamp uses an M3 screw and a hidden nut.
🧩 Part of the NEMA17 Cantilever Pen Plotter (holds X rods + X NEMA17 on the sled) kit.
