RatRig 3030 Backside Wire Bridge

I had to lay some wires from the upper to the lower side on the backside of the RatRig 4. To prevent them touching the belt, I've created this simple bridge. It snaps on the 3030 and has openings to fix the wires inside the extrusion.
Print it with the front side on the print bed, add "ears" to prevent it from moving.
