Prompt

Make a round flange as a single solid. The outer body is a cylinder of diameter 100mm and thickness 12mm, with its bottom face on the XY plane (z = 0 to z = 12), centered on the Z axis. A central through-bore of diameter 40mm runs along the Z axis through the full thickness. Six bolt holes of diameter 8mm, axes parallel to Z, are arranged on a bolt circle of diameter 75mm (radius 37.5mm) centered on the Z axis, passing through the full thickness. The first bolt hole is on the +X axis, and the remaining five are evenly spaced every 60 degrees. Output a single solid.
