Fan Duct for E3D all metal HotEnds

This is a "common" fan duct to cool the all metal HotEnds from E3D (http://e3d-online.com).
The hot end comes with its own fan duct (http://www.thingiverse.com/thing:91413) for 30 mm axial fan provided, but if you tandem the hotends too close (in this case 28 mm between HotEnds Z axis) the two ducts doesn't fit, so you can use this common one.

I made this for my custom made 3D Printer BadPrinter2 by BadDevices: check it out at http://baddevices.wordpress.com/
