Summary

Prompt

Make a flat square plate 60mm × 60mm × 8mm thick. Center it in X and Y with the bottom face on the XY plane (z = 0 to z = 8). Drill seven through-holes of diameter 5mm, axes parallel to Z, arranged in a hexagonal grid pattern: one hole at the center (0, 0), and six surrounding holes at the vertices of a regular hexagon with circumradius 15mm (distance from center to each surrounding hole is exactly 15mm). The first surrounding hole is on the +X axis, and the remaining five are evenly spaced every 60 degrees. Output a single solid.
