Clip-on side fan mount for the Printrbot Original. Clips on to the X motor mount, and uses two 1" 6-32 screws to attach a 40mm fan to the mount. Clears the print carriage when you home it.
Blows cool air past the center of the print bed, to keep a cool breeze passing by your print and print head. Helps improve bridging. Not as effective as an on-carriage fan, but it makes it easier to watch your print!
SketchUp model included for derivatives and adjustments to fit your printer, but it fits parts printed on a Prusa-Mendel and Printrbot Original perfectly!
