N50XX brushless cooling fan

thingiverse

I've created this model to cool my N5065 motor that I use on my DIY electric Longboard. It prints fast and without support. I advise you to print it with a more heat resistant material than PLA. 4 M3X20mm screws are perfect to secure it to the motor. I haven't done any testing so I have no idea which one performs the best, or if it works at all. But upon testing my motor was cooler tan usual after using them. It is not a scientific proof, but it works for me. if you print it and do some tests let me know in the comments !
