Prompt

Make a stepped boss plate as a single solid. The base is a rectangular plate 80mm × 60mm × 10mm, centered in X and Y with its bottom face on the XY plane (x in [-40, 40], y in [-30, 30], z in [0, 10]). Centered on top of the base plate sits a rectangular boss 40mm × 30mm × 8mm (x in [-20, 20], y in [-15, 15], z in [10, 18]). A central through-bore of diameter 18mm, axis parallel to Z, passes through the entire assembly from bottom to top (z = 0 to z = 18), centered at the origin. Four corner bolt holes of diameter 6mm, axes parallel to Z, pass through the base plate only (z = 0 to z = 10), located at (28, 22), (-28, 22), (-28, -22), (28, -22). Output a single solid.
