I designed this because I have a Creality extruder (https://www.amazon.com/dp/B09LQKN5WG) on my 3HOME extruders mounts; these extruders don't terminate the input side to a PTFE tube, so upon MMU unload, the filament goes everywhere and gets tangled with other lanes. This little guide mounts onto the 3HOME extruder mount (using the existing screw hole) and constrains the loose filament, feeding it into an ECAS04 connector that I can plug my PTFE tube into.
Why do this?
I have Polymaker dry boxes for my filament, but not a great place to put a filament buffer. I figured that I could add an upgraded filament guide to just before the extruder, run a PTFE tube into the drybox (locking it in place with another PTFE connecter within the drybox, so the PTFE doesn't get pulled out), and then use the drybox as a makeshift buffer. This seems to work acceptably well, and hasn't tangled so far after a few filament changes. As always, YMMV, and I'll probably change this setup after some further testing, but at least it works for now!
