extruder wheel 5mm shaft

After a few downloaded extruder wheels not fitting on my shaft I decided to design and test my own one.
Since I love airplanes I decided to incorporate a turbine fan design since I think they look cool.
I use the wheel on my Creality CR-10 4S, but it is designed to fit any 5mm shaft.

Feel free to modify this thing and use it howewer you like :)
