The prompt
Create a precise 3D model of a radioactive source containment box made of tungsten with the following exact specifications: Box Body: External dimensions: 200mm length × 200mm width × 100mm height Wall thickness: 20mm on all sides (bottom, sides) Internal cavity: 160mm × 160mm × 80mm The top opening features a multi-step labyrinth seal with 3-4 concentric stepped ridges that descend inward Each step is approximately 3-5mm deep Steps create an interlocking maze pattern for radiation containment Lid: External dimensions: 200mm × 200mm Thickness: 20mm base Features matching multi-step labyrinth pattern (3-4 concentric stepped grooves) on the underside that interlock with the box opening Each step matches the box steps with tight tolerances (0.2-0.5mm clearance for snug fit) Integrated handle on top: rectangular bar handle, 80mm long × 20mm wide × 30mm tall, centered on lid Handle has rounded edges for grip Material appearance: Dense tungsten - dark metallic gray, heavy industrial finish Design notes: The stepped labyrinth seal prevents direct line-of-sight between interior and exterior for radiation shielding. All corners slightly chamfered (1mm). Export as watertight mesh suitable for 3D printing in STL format.
