handheld microcontroller prototype 3d model

A high-realism, small handheld electronic monitoring device designed as a college engineering prototype. The device is bare electronics only, with no enclosure, no box, no casing. The device consists of: a small microcontroller board (Arduino Nano / ESP32 size) a 3-axis vibration / accelerometer sensor module (MPU6050 type) mounted close to the controller a microSD card module for data logging connected with short jumper wires a tiny OLED display showing a single numeric value labeled Fragility Score visible PCB traces, headers, and thin jumper wires All components are fully exposed, realistic, and correctly scaled. The device is placed on a clean lab desk as if ready to be attached to a test structure. Style: real-life academic prototype, student-built, not commercial. No bridge, no structure, no casing, no people, no logos, no branding, no text overlays. 🎛️ SETTINGS (USE EXACTLY THESE) Realism: High Material detail: Medium Background: Clean desk / lab table Scale: Small / handheld
