Budaschnozzel fan duct (with nut trap)

Here is a fan duct to suit a 30 X 30 mm fan and contains a nut trap for the extruder M4 bolt
To suit my x carriage variation http://www.thingiverse.com/thing:154258 ( x plate without the E3D fan holder)
Designed to be fitted on the left side but you can mirror it in your slicer software to suit the right.
Watch out for the heater cartridge and thermisitor wiring when fitting.
