The prompt
Design a professional, compact, 3D-printable electronics enclosure for a Raspberry Pi 5 and two 5V 2-channel relay modules. OVERALL DIMENSIONS: - Length: 200 mm - Width: 150 mm - Height: 65 mm - Wall thickness: 2.5 mm - Base thickness: 3 mm - Material: PETG - Rounded external corners: 5 mm radius INTERNAL DESIGN: 1. Dedicated mounting area for Raspberry Pi 5 (85 × 56 mm). 2. Four accurately positioned Raspberry Pi mounting holes. 3. Separate mounting area for two 5V 2-channel relay modules. 4. Sufficient space for wiring and cable management. 5. Keep the Raspberry Pi and relay modules separated. RASPBERRY PI ACCESS: - Accessible 4 USB ports. - Accessible Gigabit Ethernet port. - Two micro-HDMI openings. - USB-C power opening. - microSD card access. - GPIO header access. VENTILATION: - Multiple ventilation slots on the lid. - Side ventilation openings. - Ventilation near the Raspberry Pi processor. - Keep vents away from mounting screws. ENCLOSURE DESIGN: - Two separate components: bottom enclosure and removable lid. - Screw-mounted lid with four corner screw positions. - Internal mounting standoffs. - Cable entry opening on one side. - Clean, professional industrial appearance. - No unnecessary decorative features. IMPORTANT: - All cutouts must be through-holes. - Ensure all components fit without collision. - Use realistic clearances for 3D printing. - Make the design fully editable and parametric. - Export separate STL files for the lid and base, plus a STEP file. Do not invent exact relay dimensions or Raspberry Pi port positions. Make these adjustable parameters if exact measurements are unavailable.
