LED Top Panel - Snapmaker U1 LED Upgrade

LED Top Panel for Snapmaker U1 - Free

This LED Top Panel replaces the stock Top Panel while remaining compatible with the original Top Cover. It adds integrated LED channels around the front and sides of the enclosure for 10 mm LED strips, creating a clean, built-in lighting solution without modifying the external cover.

The download includes the four-piece LED Top Panel Assembly and the separate Rear HUB Panel. For a DIY setup, install your own 10 mm LED strips and connect them to a suitable power source. A plug-and-play LED kit, LED controller PCB, and Top Cover splitter cable are also available from my website (https://skylakedigital.media/skylake-lighting-system).

Download the 3MF file to see the recommended print and support settings, including painted supports for the upper floating edge of the LED channels.

Recommended materials include PETG, ASA, ABS, and other filaments suitable for temperatures up to 60C. Polymaker HT-PLA-GF may also be used, preferably after annealing. Standard PLA is not recommended.

Installation

Before beginning, turn off and unplug the printer. See Snapmaker’s top-panel removal instructions (https://wiki.snapmaker.com/u1/u1_hub_board_step6_remove_the_top_cover1.png) for reference.

1. Remove the screws securing the toolhead USB cables, then disconnect all four toolhead USB cables. Release the PTFE tubes.
