About this 3D model

Note: Due to inherint flaws in this design, I developed an alternative modular cooling system for the Prusa i3 that can be found at http://www.thingiverse.com/thing:230654. I suggest checking it out before you make one of these. This is a dual 40mm fan filament/J-Head nozzle cooler for the MakerFarm Prusa i3 with an MK IV J-Head hot end and a Greg's Accessible Extruder, although it should work with most Wade's/Greg's extruders using the MK IV J-Head. It provides 330 Degree cooling of the filament. One fan is dedicated to cooling the J-Head, the other is dedicated to cooling the filament. ********** I have added a mirrored version of the DualFanFlowDirectors360.stl file, to allow the use of 40mm X 40mm X 20mm fans for filament cooling in place of the 40mm X 40mm X 10mm fans, since they were previously obstructed by the extruder stepper motor. **********
