K8200 Extruder and nozzle blower duct for stock fan

1/3 of the air is directed straight at the extruder nozzle, 2/3 is ducted past the extruder's insulator/heatsink. I have used this with PLA with better results than standard, but not with any other filaments. -I have heard some dont require air blown on the nozzle.

Not tested with E3D heatsink type extruder since i think this may have altered dimensions (height) compared with stock. Will likely work with: http://k8200.jimdo.com/extruder/
