Prompt
Make a stepped square pyramid built from three stacked rectangular blocks. All tiers are centered on the Z axis. Bottom tier: 40mm × 40mm × 10mm tall (x in [-20, 20], y in [-20, 20], z in [0, 10]). Middle tier sits directly on top: 28mm × 28mm × 10mm tall (x in [-14, 14], y in [-14, 14], z in [10, 20]). Top tier sits directly on top of the middle: 16mm × 16mm × 10mm tall (x in [-8, 8], y in [-8, 8], z in [20, 30]). Fuse all three into a single solid.
