CORE One MMU PTFE Tube Connector (NO DRILL)

After recently converting my MK4S to the CORE One, I needed to find a way to adapt/use my existing MMU3. There are a few options to bring the PTFE tube into the CORE One from the top of the enclosure, but most of them require modification of the top plexiglass panel. As you can imagine, I had no desire to start drilling holes in the top of my brand new printer.

Inspired by a mod I recently found (by @Ruben), that modifies the top vent using a "no drilling" option for the MMU PTFE tube. It frees up one of the top vent slots to allow the PTFE tube to passthrough the top and by turning the top panel 90 degrees, it puts the open vent slot in a perfect spot. I still wanted to be able to completely close off the top vents to help regulate the chamber temperature for materials that require it, so I created a fitting that fits into the open slot and uses a backing plate and magnets to hold it in place. Including a PC4-10 fitting allows the tube to be a single piece, all the way to the nextruder.

I printed the fitting with PETG, .20mm structural, and 100% infill. The magnets are press-fit, so no glue required. You will need to use some supports on the overhang on the bottom of the top part.
