Prompt

Make a lightened disc as a single solid. The outer disc is a cylinder of diameter 120mm and height 15mm, base on the XY plane (z = 0 to z = 15), centered on the Z axis. Subtract a central through-bore of diameter 22mm along the Z axis. Subtract six through-holes of diameter 16mm, axes parallel to Z, arranged on a bolt circle of diameter 76mm (radius 38mm) centered on the Z axis, evenly spaced every 60 degrees with the first hole on the +X axis: positions (38, 0), (19, 32.909), (-19, 32.909), (-38, 0), (-19, -32.909), (19, -32.909). All holes pass through the full disc height (z = 0 to z = 15). Output a single solid.
