The prompt
A flat rectangular adapter plate: 100mm long, 70mm wide, 5mm thick. Center bore: 12mm diameter through-hole, for fan motor shaft. Four M4 screw holes for motor mounting, arranged in a rectangle: - Spaced 60mm apart horizontally, 40mm apart vertically. - Centered on the plate. - 4mm diameter each, countersunk 2mm deep from the top face. On the bottom face: two parallel mounting rails. Each rail: 100mm long, 8mm wide, 5mm tall. Rails are spaced 15mm apart (inner gap), centered on the plate width. Each rail has two 3mm diameter through-holes: one 15mm from left end, one 15mm from right end. All sharp edges: 0.5mm fillet. Material: PLA.
