Smartrap Fan alternative

thingiverse

The original text is for SmartRap printers and can be found at http://www.thingiverse.com/thing:177256. It's an alternative design based on an existing filament fan for hotends (http://www.thingiverse.com/thing:61407 by Brad Norman). The modification allows usage with a SmartRap, featuring changes to the existing hotend holder and creation of arms. While 3 arms were printed, it's suggested that one arm in a fixed position may be more effective; however, the flexibility offered by three arms was appreciated.
