Voron Micron/V0 15mm top mount LED bar with diffuser tophat friendly

None of the existing LED mounts worked for my setup, so I designed this one around the real constraints on small Vorons: tophat compatibility, minimal toolhead interference, and clearance for nozzle wiper + probe mods.

This is a top-mounted LED bar with a snap-in diffuser designed for Voron frames using 15mm extrusions:

• v0 / v0.1 / v0.2

• trizero

• micron

Key features

• Sits on top of the upper extrusion to keep the light high and out of the toolhead’s way

• Tophat compatible (no weird side protrusions)

• No glare: LEDs aim downward so you’re not staring into the strip

• Mod-friendly: designed to play nice with common nozzle wiper and probe setups

• No supports needed (prints clean as-is)

• One-piece printable on larger printers (example: Voron 2.4 bed is easy)

• If your printer is smaller: use your slicer’s cut feature and print in sections

LED strip & mounting hardware

• Designed for a 10mm LED strip

• Mounts with 2x M3 x 6mm bolts (any head style is fine)

Diffuser recommendations

I had great results with the 1mm clear diffuser printed in clear ABS—nice light output and a clean look.
Note: with clear diffusers, individual LED hot spots can still be visible depending on LED density and brightness.

If you want smoother, more “even” lighting:

• Try printing the diffuser in white (use a white filament)

• White diffusers trade a little brightness for much better blending

Why this design

The goal was a clean, practical bar that:

• doesn’t fight the toolhead,

• doesn’t block installed &future mods,

• doesn’t blast your eyes,

• and looks great once installed.
