Prompt

Make a motor mounting flange as a single solid. The main flange is a disc of diameter 120mm and thickness 12mm, base on the XY plane (z = 0 to z = 12), centered on the Z axis. On top of the flange sits a coaxial register boss (spigot) of diameter 72mm and height 6mm (z = 12 to z = 18); this raised boss is used for accurate pilot location. A central through-bore of diameter 32mm runs along the Z axis through both the flange and the register boss (z = 0 to z = 18). Four mounting bolt holes of diameter 9mm, axes parallel to Z, pass through the flange only (z = 0 to z = 12), arranged on a bolt circle of diameter 96mm (radius 48mm) centered on the Z axis at 90-degree intervals: (48, 0), (0, 48), (-48, 0), (0, -48). Output a single solid.
