Lighting assembly mechanism — modular LED panel support system

Description

This project provides a complete mechanism to mount and rotate a LED panel using stepper motors (NEMA 11). The design allows the panel to pivot 90 degrees to toggle lighting on or off for samples underneath.

All parts are designed to be lightweight, modular, and compatible with standard mechanical fasteners, allowing quick assembly and maintenance.
