PrintrBot Chassis Mounted Blower Fan Kit

thingiverse

I wanted to upgrade to a blower fan but I didn't want all that extra weight on my print arm. So I went ahead and modeled/printed all the fittings to mount the blower fan to the chassis and duct the output to my extruder/hot-end. The mount for the hose to the shroud should work with any choice of shroud. The only part that's PrintrBot specific is the shroud itself. The hose is from a vacuum that I picked up from a thrift store. Make sure you use an extremely pliant hose if you print this. Otherwise it's rather counterproductive. Note: this is a WiP; I haven't gotten around to designing the blower fan chassis mount yet (I'm using zip-ties at the moment). Custom Section non-printed things needed: 1x 1.25in diameter hose length 1x 12V Brushless Motor (here's the one I used: http://www.amazon.com/gp/product/B00B2ARV22?psc=1)
