Anet A8 tornado fan

I wanted to try a fan which didn't blow directly on the extruder. The idea here is to create a circular airflow. The design is a bit rough in places, it could do with tidying up to prevent some small holes.

Building with supports might be necessary if you use the stock cooling nozzle whilst making this (on the bed only - there is enough internal support)

I'm suggesting people build this now, rather than pursuing development of my own fan. http://
