trouble loading filament?
no more with this all in one titan bowden extruder fitting.
it is a bowden coupling and titan extruder adapter in one piece.
no more cutting 45° angle and straighten the filament and curse until you get it eventually into the Bowden tube.
loading the filament is easy and the original ptfe tube coupling will fail on you at som time.
this will fix the problem.
I used PETG for strenght.
