Summary

Prompt

Make a flanged hollow shaft as a single solid. The base is a circular flange of outer diameter 80mm and thickness 10mm, with its bottom face on the XY plane (z = 0 to z = 10). Above the flange and concentric with it sits a cylindrical shaft of outer diameter 30mm extending 50mm upward (z = 10 to z = 60). A central through-bore of diameter 15mm runs along the Z axis through both the flange and the shaft (z = 0 to z = 60). The flange has four bolt holes of diameter 6mm, axes parallel to Z, on a bolt circle of diameter 60mm (radius 30mm) centered on the Z axis. The first bolt hole is on the +X axis; the others are spaced every 90 degrees. The bolt holes pass through the full flange thickness. Output a single solid.
