Tevo Black Widow Nozzle Fan Duct

This is a maker-designed and tested nozzle fan duct specifically for the Tevo Black Widow with stock hot end, and has 360 degree cooling.

It incorporates fittings for thread inserts for a 40x40mm fan, and a 5mm hole for the mounting bolt. I suggest you research the required fan speeds for your desired print quality.

See photos for assembly, fitting, air flow illustration, and print suggestion. (print shown didn't have a fitted nozzle fan, and used stock stepper drivers)

Dimensions: 41mm
