Fan Duct Bracket For The Printrbot+ LC

thingiverse

This bracket, designed for Ultibots' or AeroMonkeyDork's fan duct derivatives, mounts on a laser-cut Printrbot Plus extruder mount. However, an update (3/22/2013) revealed two issues: the 40mm fan used is not sufficiently cooling and the bracket arm causes the duct to be too high above the nozzle. Solutions include using a more powerful fan and shortening the arm or adding a joint. To assemble, print the bracket, articulated arm parts, fan duct, and use a 40mm fan with long leads, along with (2) longer screws for attachment to extruder and (4) nuts/bolts for bracket arm joints. The snug fit of the fan duct between the laser-cut extruder mount's uprights can be resolved by applying pressure; however, improvements in dimensions may be needed due to other attachments like bed levelers or clips.
