Light Bar Wiring Conduit - Ender 3 V3

prusaprinters

The new Light Bar for the Ender 3 V3 SE is OK, except they leave you hanging on how to run the wires to the Motherboard. The instructions don't mention that you need to drill a ¼ inch hole in the top of your right Z-rail. Which if you screw up, would imply it's covered under warranty… NOT! Plus I didn't want to take off the gantry and risk misaligning something. This alternative uses 1/8 inch Split Wire Loom (Amazon) and three printed parts. The clips all just snap-in… The hardest part of this install is getting the wire into the conduit; Cut a 2 foot (24 inch) length, you can trim later.  And make sure it's split ahead of time. Use a butter knife or something to open the split and work the wire in a little at a time..Update 12/21/23 - Added an STL for the Conduit Passthrough flipped 180 degrees; This will put the Supports where they are easy to remove vs. digging them out of the inner area with those delicate mounting tabs.
