Y Motor End Block
The Y motor end block for the 'NEMA17 Cantilever Pen Plotter' kit. It anchors two 8 mm Y rods at 60 mm spacing in 25 mm deep pinch-clamp sockets, each tightened with an M3x16 screw and a captured M3 nut. It also holds the Y NEMA17 on a 5 mm vertical wall (31 mm M3 bolt square, 22.4 mm teardrop pilot hole) and sits on the desk as a 102 x 77 mm foot. The base is pocketed to save material, and the GT2 belt channel between the sockets stays clear.
