Replicator 2 Cockpit

This replaces the OEM part for which I have yet to figure out the name of, so I've taken to calling it the cockpit. There are a few already out there. They hold the blower fan and filament tube for the Replicator 2 extruder. There were a few tweaks I was always left wanting. I finally got out the caliper, pen and paper and made one from scratch.

It resists melting fairly well. It also gets down with the cable management action via the cable tie routing. I wouldn't call it feed tube friendly.

* whpthomas' Downward blower duct: http://www.thingiverse.com/thing:140254
*4/30/14* Added Step model for those wishing to customize the design.
*6/13/15* Added a file for models that shipped with the shorter 5mm mounting screws.
