Prompt

Make a circular flanged cap. Outer cylinder: outside diameter 60mm, height 8mm, axis along Z, base on the XY plane (z = 0 to z = 8). Concentric central through-hole of diameter 40mm, axis along Z. Six bolt holes of diameter 5mm on a 50mm bolt circle (radius 25mm from the axis), evenly spaced starting at 0 degrees, all parallel to Z and going fully through. Output a single solid.
