This provides a front blower fan mount and fan duct for the wanhao i3,
while leaving the nozzle unobstructed.
Support material can be used, but not internally. I haven't tested PLA,
but I doubt it would work without the part warping or drooping during use.
Print with PET, ABS or any other filament that can withstand the heat
from the hotend.
The 2 M3 Screws that mounted the stock fan work fine for mounting it,
you will also need 2 M3 nuts, an M4x20mm screw, and an M4 Nut.
The 2 fins that help to hold in the blower fan are quite fragile, be
careful with them.
I've tested this on my Wanhao di3 v2
