Light Rail Endcap with Filament guide attacher

thingiverse

I prefer the sleek look of a light bar but I've opted for a filament guide that perfectly fits onto the crossbar, after customizing the endcap to accommodate it seamlessly. This setup is ideal for users who position the light bar at the back with the cable exiting from the right front or vice versa, with the bar facing forward and the cable emerging from the right rear.
