This is an LED channel I designed to snap-mount onto V-slot wheel standoffs behind the X-Axis gantry.
The lighting angle is adjustable; you can tilt and tighten the channel to suit your needs.
I used this LED kit from Amazon, but it should work with any LED strip that's <12mm in width:
I used a clear filament for the channel cover which helps soften the lighting.
I'd advise using a fairly high infill so that the arms don't break when snapping onto the spacers.
You'll want to print the caps twice - once mirrored in X
The channel components slide-fit together.
2x M3 screws and nuts are needed to attach the arms to the channel.
