Prompt

Make a single solid: a flat plate 60mm × 60mm × 12mm, centered in X and Y with the bottom face on the XY plane (z = 0 to z = 12). Drill four counterbore holes at corners (20, 20), (-20, 20), (-20, -20), (20, -20). Each counterbore consists of two coaxial Z-aligned through-features: a clearance through-hole of diameter 4mm running the full thickness (z = 0 to z = 12), and a coaxial recess of diameter 8mm machined 4mm deep from the top face (so the larger diameter spans z = 8 to z = 12). Output a single solid.
