This remix was constructed aka. hacked to provide proper part cooling flow with 40mm axial fan when using cr-10 heavy duty mod. There are two files, one for E3D v6 and one for E3D Volcano hotend.
For Ender-4 Printer:
The top mounted fan allows extra side clearance to the longitudinal upper eextrusion profiles, thus gaining print area compared to side mounted fan constructions.
Please leave feedback about fitting and performance.
