Prompt
Make a 30mm cube. Center it in X and Y, with the bottom face on the XY plane (z = 0 to z = 30). Drill nine through-holes of diameter 3mm, axes parallel to Z, arranged in a 3×3 grid on the top face spaced 8mm apart in both X and Y, centered on the Z axis. Hole centers are at (x, y) = (-8, -8), (0, -8), (8, -8), (-8, 0), (0, 0), (8, 0), (-8, 8), (0, 8), (8, 8). Output a single solid.
