The prompt
Create a simple 3D CAD model of a compact smart fan controller enclosure for a project called ComfortIQ. Design a rectangular wall-mounted enclosure, 120 mm wide, 80 mm tall, and 40 mm deep, with 2 mm thick walls. Include: - A removable front lid with four screw holes - Ventilation slots on the sides - Internal mounting points for an ESP32 microcontroller - A small opening for a temperature and humidity sensor - A cable entry opening at the bottom Use a clean, modern smart-home design. Make the enclosure suitable for 3D printing and export it as an STL file.
