The prompt
Create a separate hollow electronics cap for the top of a rectangular desktop crate radio. Base footprint 140 mm wide by 127 mm deep, approximately 40 mm tall, with a sloped roof but a flat rectangular bottom. Use 3 mm walls and a removable lid. Leave interior space for one ESP8266 development board, two small audio amplifier boards, a USB-C PD trigger module, wiring, and a volume potentiometer. Add a potentiometer shaft hole on the front and a USB-C power opening on the rear only. Include mounting bosses and ventilation slots.
