Blower Fan duct for PrinterBot Simple Metal, vertical, more improvified

thingiverse

Credit to SpannerHands for inspiration and his nozzle, which I've included unaltered here for convenience. (If you're looking at nozzle alternatives, read Desi Quintans' nozzle study: http://www.desiquintans.com/coolingtests.) However, I didn't like the sideways mounting of the fan, so this duct moves it to a vertical and fore-and-aft position. (Incidentally, I sliced this using pretty aggressive settings in Cura's Fuzzy Surface feature; that's why it looks fuzzy in the picture.) ETA: In case your slicer doesn't have a "lay flat" tool, I've added a copy of the STL rotated into proper printing orientation. ETA: I was experimenting with Sigsmond0's cable chain (thing:1060522), and the part E_motor_mount just barely clears the duct. I added a more clearance version to move the fan out a few millimeters. I've left the original, but recommend using this version, as there doesn't seem to be a downside.
