The prompt
**UPDATE EXISTING DESIGN — RASPBERRY PI 4 MODEL B (2GB)** Modify the existing Raspberry Pi enclosure to accommodate a Raspberry Pi 4 Model B with 2GB RAM instead of Raspberry Pi 5. **Keep the existing enclosure:** - External dimensions: 200 × 150 × 65 mm - Base thickness: 3 mm - Wall thickness: 2.5 mm - Two separate printable parts: base and removable lid - Existing rounded corners, lid screw positions and ventilation concept **RASPBERRY PI 4 MOUNTING** - Board dimensions: approximately 85 × 56 mm - Four mounting holes - Nominal hole-centre spacing: 58 × 49 mm - Board mounting-hole diameter: 2.7 mm - Use suitable M2.5 mounting hardware. - Adjust the existing standoffs to match the Pi 4 mounting pattern. - Verify all four holes against the official Raspberry Pi 4 mechanical drawing. **UPDATE ALL PORT OPENINGS** Provide access for: - 4 USB ports (2 USB 2.0 and 2 USB 3.0) - 1 Gigabit Ethernet port - 2 micro-HDMI ports - 1 USB-C power port - 1 3.5 mm audio/composite jack - microSD card access - 40-pin GPIO header access Position all openings according to the actual Raspberry Pi 4 Model B board layout. Do not reuse Raspberry Pi 5-specific port positions. **INTERNAL DESIGN** - Retain mounting space for two 5V 2-channel relay modules. - Keep the Raspberry Pi and relay modules separated. - Preserve adequate wiring space and cable routing. - Keep ventilation near the processor. - Allow room for a heatsink or cooling accessory if required. **IMPORTANT** - Do not change the overall enclosure dimensions unless necessary. - Do not invent port dimensions or positions. - Keep all mounting features editable. - Check component clearances and lid interference. - Export the base and lid as separate STL files and provide a STEP file.
