Summary

Prompt

Make a square plate 80mm × 80mm × 6mm (X × Y × Z). Center it in X and Y, with the bottom face on the XY plane (z = 0 to z = 6). Drill one central through-hole of diameter 12mm on the Z axis, and four corner through-holes of diameter 6mm with axes parallel to Z, centered 10mm in from each corner of the top face. Output a single solid.
