Prompt
Make a flanged disc with a raised hub as a single solid. The outer flange is a cylinder of diameter 100mm and height 10mm, base on the XY plane (z = 0 to z = 10), centered on the Z axis. Concentric with the flange and sitting on top of it is a raised hub cylinder of diameter 40mm and height 20mm (z = 10 to z = 30). A central through-bore of diameter 18mm runs along the Z axis through the full combined height (z = 0 to z = 30). Six bolt holes of diameter 8mm, axes parallel to Z, pass through the flange only (z = 0 to z = 10), arranged on a bolt circle of diameter 75mm (radius 37.5mm) centered on the Z axis, evenly spaced every 60 degrees with the first hole on the +X axis: positions (37.5, 0), (18.75, 32.476), (-18.75, 32.476), (-37.5, 0), (-18.75, -32.476), (18.75, -32.476). Output a single solid.
