Ender3 Triple LED Light Bar

Triple 10mm LED Light Strip to fit Ender3 and probably other models.

I created 2 versions, one with diffusers & one without diffusers. The diffuser was remixed from https://www.thingiverse.com/thing:3409969. Print in clear PETG if you can, white PETG works well also. White PLA is also OK but blocks more light.

I added a lamp shade to the front and modified the endcap to match

I added a little support from the endcap to prevent the mount from sagging (hopefully) from the heat of the LEDs.

NOTE: Ender3s generally have a 24v power supply. You must use a DC/DC converter to drop the voltage down to your LED strip's voltage (if you're not using 24V LEDs). I use an LM2596 based adapter. This allows you to adjust the voltage down to a bit lower and run the LEDs cooler. Here is my remix of the LM2596 mounting box - https://www.thingiverse.com/thing:5798008 and here is a DC converter - https://www.aliexpress.com/item/1005004910023504.html
