40mm Fan Blade Replacement

#WARNING: THE CODE GENERATES A FAN IN THE WRONG ORIENTATION. YOU MUST MIRROR THIS IN THE SLICER#

I used the basic code generated by Rennat, but loaded it into OpenSCAD to modify the part of the fan where the magnet goes.

I increased the blades from 9 to 11, and I am not completely sure the blade pitch is the same, but it does the job of cooling. It is also much quieter. I could hear the old fan downstairs, I can now notice the fan when I'm in the room.

I had a blade break off the main fan, and I didn't feel like spending $7+ to get a new fan. This may actually have been better due to the noise reduction.
