Prompt
Make a square block 60mm × 60mm × 10mm. Center it in X and Y, with the bottom face on the XY plane (z = 0 to z = 10). Drill eight through-holes of diameter 5mm, axes parallel to Z, on a bolt circle of radius 20mm centered on the Z axis. Holes are evenly spaced every 45 degrees, with the first hole on the +X axis. Output a single solid.
