3D Printable Air Duct for Centrifugal Part Cooling Fan
grabcad
This is a 3D printable part cooling fan air duct for a centrifugal fan that connects to the side of the MK8 direct drive extruder hot end. It is modeled to direct the air right underneath the heater block. I removed the original hot end cooling fan and mounted a centrifugal part cooling fan in its place, as I have a water cooling loop that cools the hot end. Changing the dimensions of this part will most likely require modifying the sweep and loft features. Printed with ABS using support material.
