Cable rail for Ender 3v3 KE vertical beam

The picture shows a PTFE tube attached along which the filament is brought from the spool holders below the printer. On the other side of the printer, I run the LED light cable up along the cable rail.

Two different versions for both sides, 45 degree angle and 33 degree angle brackets. Same cable rail fits both.

The cable rail is attached to the brackets with a small bead of instant glue. The brackets attach themselves to the vertical beam (if the print is loose, you can put thin double-sided tape between the bracket and the beam, or instant glue if you prefer).

If you are not attaching any heavy cables, 15% infill is fine, the material doesn't matter that much for printing. No supports are needed anywhere.
