SethBon's LED light bar is a great design, but I didn't really like how the power cable was loose at the back of the printer.
I designed a guide that holds the sleeved (or unsleeved) cable against the frame, and and thin enough to not interfere with any moving parts.
For the sleeve, I used 1/4" (6.35mm) PET: https://amzn.to/2M7FPm1
The screw is an M3x10mm, which is available in the Prusa spare parts bag (5.3x3mm head) or here: https://amzn.to/3KMpnSo
Print Instructions
Print "body.stl" and "side_lock.stl" in the orientation seen on the build plate screenshot. "body_without_lock.stl" not necessary.
Layer Height: 0.20mm
Infill: 20% Rectilinear
Supports: None
Assembly
Place the round profile of the side_lock (tab facing down) into the matching cutout on the body piece.
Insert M3x10mm screw through the hole, connecting both pieces.
Tighten onto the back of the printer frame, ensuring that the sleeved cable is not pinched and the side_lock is hugging the inside of the frame.
I've also include a version of the body that doesn't need the side lock: "body_without_lock". Might need to be pretty tight so it doesn't rotate on the frame...
