The prompt
A 3D mechanical assembly of a wheel nut loosening detection system. The core of the model features a threaded joint with an existing wheel nut tightened onto it. A custom magnetic indicator cap is securely fitted directly over this wheel nut. A small magnet is integrated into the cap so that it rotates simultaneously with the nut. Positioned adjacent to the cap is a Hall-effect sensor, oriented to observe the magnetic field response across a small air gap. The Hall-effect sensor is wired to a nearby embedded processing unit representing an ESP32 monitor. Connected to this ESP32 board are compact output components, specifically a small OLED screen, an LED, and a buzzer for warning alerts
