Prompt
Make a flat bar with a stadium-shaped (rectangle with semicircular ends) footprint, extruded 10mm along Z. Total end-to-end length is 80mm along X; total width is 20mm along Y. The footprint is the union of a 60mm × 20mm rectangle (x in [-30, 30], y in [-10, 10]) and two semicircles of radius 10mm centered at (-30, 0) and (30, 0). The bottom face sits on the XY plane (z = 0 to z = 10). Output a single solid (no holes or other features).
