40mm fan scoop

SummaryThis fan duct is designed for Jonas Kuehlings X-Carriage and the design is also based on his. Since he hasn't shared any of his fan scoops, I tried to make my own. UPDATE fanductv3.1.stl is the latest model. It directs the airflow better down at the printed object rather than the nozzle. The height is designed for Reprapfab's or Reprap Austria's hot ends, but should work with others too,InstructionsPrint, install and test. I think these are a must even for abs. Comment! Next one is on it's way, what should be in it?
