40mm Extrusion Fan Duct for Prusa i3 K Extruder w/E3Dv6

thingiverse

Here is my first attempt at designing a compact extrusion fan duct for an E3Dv6 hotend fitted with a K style extruder. As of now, I've left out key components like the motor, E3D heat sink fan, and additional plastic parts of the extruder from the mockup picture - I'll be incorporating them later on. For now, use Fan_Duct_1ver6 available in the files section as a reference design. Version 1.0 of this design actually functions and showcases decently concentrated air flow. It represents a considerable step forward compared to its predecessor 1ver4b. In fact, version 6 incorporates a refined vent system that helps distribute airflow onto the print with remarkable efficiency.
