Prompt

Make a stepped pyramid composed of three concentric square layers stacked along Z, fused into a single solid. Base layer: 80mm × 80mm × 10mm, centered in X and Y, bottom face on the XY plane (z = 0 to z = 10). Middle layer: 60mm × 60mm × 10mm, centered, sitting on top of the base layer (z = 10 to z = 20). Top layer: 40mm × 40mm × 10mm, centered, sitting on top of the middle layer (z = 20 to z = 30). The base layer has four bolt holes of diameter 6mm, axes parallel to Z, drilled through the full 10mm thickness of the base only (z = 0 to z = 10), located at (30, 30), (-30, 30), (-30, -30), (30, -30). Output a single solid.
