COB Led Strip Mount – Contained Illumination for Voron Trident and 2.4

LED Strip Holder – Light-Blocking Remix

This project is a remix of the LED strip holder included in the LDO kits for COB LED strips used to illuminate the printer chamber.

The goal of this modification is to restrict vertical light spill, helping to contain the illumination inside the printer enclosure.
The original design allows a significant amount of light to escape upward, often illuminating the ceiling and the surrounding room. This remix redirects and blocks that light so it remains inside the enclosure where it is actually needed.

In addition, this design prevents direct visibility of the LED strips, avoiding glare and eye discomfort when standing in front of the printer.

⚠ Important Note on Light Intensity

Because part of the emitted light is intentionally blocked, it may be necessary to increase the LED brightness to compensate for the light loss compared to the original holder.

 Reference Setup

The photos show a Voron Trident 250, using:

• One 150 mm LED strip per side

• This configuration already provides sufficient chamber illumination while keeping light contained

Available Parts & Configurations

All parts are designed for 150 mm segments and are provided in two different types:

1-Front Holders (with light stop)

• Include a front stop that fully hides the LED strip

• Completely blocks forward-facing glare

• Used at the front of the printer

2-Continuous Extension Holder

• A longitudinally continuous piece

• Allows extending the LED strip length to 300 mm

• Can be used on either the left or right side

Included Parts Summary

• 2 parts for the front left holder

• 2 parts for the front right holder

• 2 parts to extend the LED strip length (usable on either side)

This modular approach allows flexible configurations depending on the desired LED length and printer size.
