Summary

Prompt

Make a regular pentagonal prism. The cross-section is a regular pentagon centered on the Z axis with circumradius 15mm (distance from center to each vertex). Orient the pentagon so one vertex points in the +Y direction. Height 25mm along Z, base on the XY plane (z = 0 to z = 25). Drill one through-hole of diameter 5mm, axis parallel to Z, with its axis offset 5mm in the +X direction from the center (so hole axis is at (x=5, y=0)). Output a single solid.
