120 mm Fan Air Flow Optimizer/ Flow Rectifier / Nozzle

Did you 3D print this model?

3D model description

My contribution to the unofficial fan accessories challenge, made a kind of “flow rectifier” (or nozzle like piece of kit) for a 120 mm fan to avoid turbulences and a cone shaped airflow. Need to print this one tomorrow, used the same design for a different fan and it worked great, pretty sure this will work as well.

Update: Printed and tested, works great! Extends the range of a standard fan (pictures) to more than 1,2 m! PLA print.
