The prompt
Generate a 3D CAD model of an electronic enclosure box. Outer footprint: 94mm length by 69mm width, height: 45mm. Shell the box with a 2.0mm uniform wall thickness, leaving an inner footprint of 90mm by 65mm. Add a 1.5mm deep x 1.5mm wide continuous groove (drip lip) around the top perimeter edge. Inside, add a 2.0mm thick internal partition wall across the 90mm width dividing it into a 30mm top chamber and a 32.5mm bottom chamber, with a 5.0mm center hole. In the four inner corners, add M3 screw bosses. In the bottom chamber, add four circular standoffs for an ESP32 board. In the top-left chamber, add four standoffs for an MQ-2 sensor. In the top-right chamber, add two vertical U-channel guide rails for a DHT11 sensor. Add a USB port cutout on the right wall and ventilation slots on the left and right walls.
