Sunhokey Prusa I3 fan duct 2015

Summary This is a remix of another fan duct made for the Sunhokey Prusa I3. This has had the bolt flange modified for the smaller bearings on the x axis on the 2015 version of the printer. I have added lots of room up or down to the flange to allow for shortter or taller extruders . My bearing housings we not threaded all the way through I simply used self taping metal screws to attach it to the bearing holder.
