I have my filament routed from my dryer box to my extruder with some leftover capricorn tubing. I made this to keep the tubing against the extruder arm during retractions - the tubing was moving and allowing filament to contact the z rod. I printed as the model is oriented - no supports required. The slot will allow you to remove and install this part without removing your filament.
I added a V2 that will allow for a zip tie for additional security. This one will require a thin support to print.
The author marked this model as their own original creation.
