Prompt
Make an octagonal prism flange. The outer cross-section is a regular octagon with flat-to-flat distance 40mm (apothem 20mm), oriented so two flats are parallel to the X axis (the top and bottom of the octagon). Height 8mm along Z, base on the XY plane (z = 0 to z = 8). Drill eight through-holes of diameter 5mm, axes parallel to Z, on a bolt circle of radius 15mm centered on the Z axis. The first bolt hole is on the +X axis, and the rest are evenly spaced every 45 degrees. Output a single solid.
