Simple toroidal Propeller

It's more about playing with openscad than building a multicopter, even if I often think about doing this..

However, here's the Parameters:

BLADECOUNT : This is the number of blades
BLADESIZE : This is the length of a blade
RATIO: If you want the blades to be not as wide as long, this is how much smaller they're going to be ( scale 1/RATIO)
HEIGHT : The height of our prop
ANGLE : The angle of the propeller blades
WIDTH : This is material thickness of the blades
CENTERWIDTH : Width of the hub
CENTERHOLE : The mount hole for the axis

Didn't try to print yet.

Have fun :)
