Fancy Ripcord Flyer Blades (parametric)

My take on the ripcord flyer blades for the amazing thing 3867577 from thjelmfelt with the following design goals:

• better looks
• use a proper air foil
• slightly more weight on the outer ring to increase rotation energy
• proper twisting of the blades to get constant pitch over the full blade
• smaller profile on the outer side to account for higher velocity and to reduce lift-induced drag
• printable without supports
• fully parametric design

The 80mm pitch variant has quite some overhang on the outer blades. The printing quality without supports was still acceptable.

The freecad file is included and you can easily adapt the design by changing values in the config sheet. With extreme values, the top level "filet" might break and has to be fixed or removed.

If you print other versions, then please let me know how they fly!
