Parameters
facets: defines the number of facets by default. In other words how smooth the propeller will be.
blades: the number of blades
height: total propeller height
blade_length: blade length or total radius. If you have a 5'' drone set this to 63 (mm).
blade_width: blade width
blade_thickness: blade thickness. Be aware of your printer capabilities.
blade_hole_offset: displacement between outer and inner sides of the blades. It shouldn't be greater than thickness.
blade_attack_angle: this sets how is going to be the attack angle. A positive value will generate a CW propeller and a negative one a CCW.
blade_offset: blade distance from propeller axis
safe_blades_direction: indicates if a blade must delete itself from getting into the previous or the next blade.
