9-blade fan blades

Fan blades for mini electric motors. Please use more than 5V of power for this or it would be too heavy and cannot perform its best.

The hole in the bottom is 1.12 millimeters in radius(It should end up fitting tightly onto a motor of 1 millimeter radius). If it is too tight, try to push it onto the motor back and forth a few times and the hole should widen. The hole is also 5 millimeters deep. If you can, don't use a brim because it will be hard to remove and probably affect the efficiency of the blades. Also you want to make sure that you don't print it using faster speeds than Normal to prevent cooling problems.

I have provided STL, 3MF, and STEP raw files if you want to customize it for your own use!
