The prompt
Create a modular, stackable and expandable 3D-printed shelf system. Overall dimensions of one module: - Width: 186 mm - Depth: 200 mm - Height: 150 mm The system consists of: 1. One lightweight, reinforced shelf plate. 2. Four vertical support posts with a square cross-section of 5 × 5 mm. 3. Integrated plug-in connections between the shelf and support posts. Shelf construction: - 2 mm top surface - Approximately 5 mm reinforcing ribs underneath - Open ribbed structure to minimize material usage - Four integrated corner mounting points Modularity: - Multiple modules must be stackable vertically. - Multiple modules must connect horizontally. - Use identical, interchangeable support posts. - Use secure but removable plug-in connections. - Allow optional adhesive bonding. The design must be optimized for FDM 3D printing with a maximum build volume of 220 × 220 × 250 mm. Create a complete assembly with separate, editable components. All parts must be dimensionally accurate and mechanically compatible. Export individual STL files and a complete STEP assembly.
