Centrifugal fan
grabcad
I was trying to get around not designing one and found this site, but with the sizing that i need i went ahead and just made one. I haven't done any cfd testing on it and wish i could but i will be 3d printing this to run actual test and then re optimize. In the file the motor that i will be using is also included in the sizing.
