The prompt
Create a 3D CAD model of a student-level CNG gas leakage detection prototype for a mechanical engineering final-year project. Use a rectangular base plate 300 mm × 200 mm × 5 mm. Place an Arduino Uno, an MQ-4 gas sensor module, a buzzer, red and green LEDs, a small display, and a prototype demonstration valve on the base. Add simple mounting brackets and a protective enclosure. Show all parts clearly separated and label each component. Keep the design compact, realistic, and suitable for a college project presentation. This is a non-operational laboratory demonstration only, with no live CNG connection and no functional fuel shutoff system.
