Prompt

Make a compound boss plate as a single solid. The base is a rectangular plate 120mm × 80mm × 15mm, centered in X and Y with its bottom face on the XY plane (x in [-60, 60], y in [-40, 40], z in [0, 15]). Two cylindrical bosses of diameter 30mm and height 20mm rise from the top face of the base plate: the left boss is centered at (-30, 0) and spans z in [15, 35]; the right boss is centered at (30, 0) and spans z in [15, 35]. Through each boss and through the base plate below it, drill a coaxial through-bore of diameter 16mm along the Z axis: the left bore is centered at (-30, 0) and passes through z in [0, 35]; the right bore is centered at (30, 0) and passes through z in [0, 35]. Four corner bolt holes of diameter 8mm, axes parallel to Z, pass through the base plate only (z = 0 to z = 15), at positions (50, 30), (-50, 30), (-50, -30), (50, -30). Output a single solid.
