Geeetech prusa i3 fan duct

First release of my geeetech prusa i3 fan duct. This thing is still in work.

Others fanducts for geeetech are on sides and touch endstops, so I put mine in front of my extruder. Moreover, my fan duct is in two parts : this way I can easily change the cooling nozzle, and you guys, can create your own cooling nozzle easily ;)

UPDATE (30/07/2015) :
- add nozzle adjust
- add nozzle rotated

NEXT :
- add more nozzle !!
