Duel Extruder fan duct

thingiverse

This is a fan duct for a Geeetech I3 Pro C duel extruder. It works with 40mm X 40mm fans. It just slides onto the metal duel extruder bracket that came with my printer. I scaled up the original model before I uploaded it because I usually have a lot of shrinkage. It's a little loose. I printed this in PLA because I had no other kind of filament. If it works out well I'll probably buy some nylon to print it out of. READ NEXT I just wanted to update this with more information. As a newbee to 3D printing I wasn't aware my printer had to be calibrated after I assembled it, so I scaled up the fan duct to anticipate probable shrinkage, but it wasn't shrink it was just incorrect calibration. So if anyone prints this at this size, it will be loose. You may want to scale it down by .98 NEXT I just added the Parasolid file, just in case any one might want to improve on this model.
