Venturi inlet for 80mm PC FAN

This is a intake side 8cm PC FAN holder for ease air intake.

I made this for mosquito trap to test how funnel design affect to wind velocity, and found actually such design is quite effective to maximize wind speed and reaching distance even such a very slow air speed with quiet = small air pushing PC FAN of 20CFM or less .

rough remix of original Anet A8 design by Woodreff (thanks for sharing the great design)
