Bukoschnozzle Circular Fan Duct REDUX

Circular fan duct based on http://www.thingiverse.com/thing:69557 modified to allow for a 40mm fan. Fits Bukobot 8 V1 (pre-"spitfire" extruder). M3 screws fit, but are a bit tough to thread in due to scaling of the back of the mount when it was adjusted. Made from blue PLA from ORD Solutions.
