The model is based on the well known "Delta P Fan Duct" and it ensures one handed nozzle changes by blocking rotational force, designed exclusively for Phaetus Dragon HF or Phaetus Dragon normal flow hotends. It has been also printed & tested and the results are very good, hence why I'm publishing this model. I recommend printing with ASA, PC and other similar materials for the best long term result, PETG might creep or melt in the lower area. It can be used with my other design: https://www.printables.com/model/267330-phaetus-dragon-hf-extruder-body-remix-easy-nozzle-. Have fun !
