A pass through guide to hold 2 PTFE tubes and 1 6 pin BUS cable for Bambu AMS. I have the Harbor Freight 48” desk which is what this is designed for, but it will work for any surface with a similar thickness of .35” or 9mm or thinner. To install you must drill a ¾“ (or 19mm) hole in the surface you want to pass through, and then route your 2 PTFE tubes and BUS cable through the 2 pieces and then assemble it to the mounting surface and you’re done.

This part goes hand in hand with my AMS holders designed for the top shelf of the Harbor Freight desk
