Sunburts Fan Blades

For the FanShowdown by Major Hardware - my second design with a more traditional structure.

Printed in PLA at .2mm layer height with supports for the blades and this thing really moves some air. There is almost zero turbulence out of the front of the blades unlike my last design and this seems much quieter as well. I'm using it on a Artic 120mm fan that I cut down to fit as I don't have an a12x25 to test it on.
