Wall mount ptfe tube/filament holder for MMU2

I put my spools on a shelf, then had them feed in backwards.

So by using these, the PTFE tube stays stuck, but filament goes in smooth, just guides it

edit2: i decided to use the festo version for mine anyway, except it's upside down. the tube makes it easier to feed through on the top, and it doesnt get tangled on the bottom. best of both worlds so far. so if you use it, try to match it like my picture for best results. i use these gold bowden extruders. (note, i have a ptfe tube coming
