21 BOXES - 120mm fan

My 2nd submission for Major Hardware's Fan Showdown on Youtube. Designed in Sketchup in about 30 mins. It actually got on the board (until the next round of entries haha).

This is a 120mm fan that can fit on a bare Noctua 120mm fan hub. It has 21 boxes spread across 7 "blades" at 21 degrees for a total of 42 lifting surfaces.

My plan was to eventually do something similiar with other basic shapes (triangles, circles, etc).

Feel free to print for your own use or testing.
