Prompt
Make a flat rectangular plate 80mm × 40mm × 8mm thick, centered in X and Y with the bottom face on the XY plane (so it spans x in [-40, 40], y in [-20, 20], z in [0, 8]). Cut a stadium-shaped (rectangle with semicircular ends) slot all the way through the plate, axes along the X direction. The slot has total end-to-end length 50mm and width 10mm: the centers of the two semicircular ends are at (-20, 0) and (20, 0), each of radius 5mm, joined by a 40mm-long, 10mm-wide rectangular section (x in [-20, 20], y in [-5, 5]). The slot is cut through the full plate thickness. Output a single solid.
