This is a custom LED lighting support designed for the Creality Ender 3 Neo. It may also fit other Ender  models that use a similar top-frame extrusion, but please check the dimensions before printing.

The mount holds two 12V COB LED bars and includes space for an ON/OFF switch measuring approximately 10 × 15 mm.

The lights are powered by an external 12V battery, so there is no need to connect them directly to the printer’s power supply. This makes the installation simple and keeps the lighting system independent from the printer electronics.

Assembly
The connection between the left/right supports and the central bar is designed to be flexible. The parts can be glued together for a permanent and rigid installation, or they can be left unglued, allowing you to adjust, modify, or replace the central bar later.

Before applying glue, it is recommended to test-fit all parts and verify the final position on your printer.

This setup provides better visibility of the print area, making it easier to monitor prints, record timelapses, or detect problems before they become a spaghetti festival.

Important: Check the polarity, voltage, and current requirements of your LED bars before connecting the battery.
