Da Vinci 2.0 Rear mount cooling fan shroud

UPDATE. I actually don't like this thing anymore. It kept getting caught on the screws on the back of the bed. So I have made a better design that attaches to the front. http://www.thingiverse.com/thing:553792 This fan shroud will attach to the back of the Da Vinci 2.0 tool head. This is for the Dual Fan model. It redirects air from the second fan to cool the extruded plastic. Please note that repurposing one of the two fans does reduce the cooling to the extruders. I am working on another fan shroud to address that problem. I recommend you use custom firmware to control the fan that you attach this to. See the instructions for more information. I lowered the aim of the left nozzle.10/6/2014 It was too high.
