The prompt

Create a 100 × 60 × 20 mm rectangular block. Add four 8 mm through‑holes, one near each corner, 10 mm from each edge. Add a 2 mm chamfer on the top outer perimeter. Add a central 20 mm diameter counterbored hole: 10 mm deep counterbore at 30 mm diameter, then a 12 mm through‑hole. Fillet all vertical edges at 3 mm. Export as STEP and STL.
