Parametric Folding Propellor Generator

I have an *FPV Shadow* RC plane from *Banggood* that I bought a while ago. The standard kit includes a bunch of 6 inch diameter x 4.5 inch pitch propellors. For a while I would break a prop (and often rip the motor off) each time I landed because there was nothing to stop the propellor motoring over or being in a vertical position when it touched down. I alleviated the problem by adding two largish coreflute tails that extended below the plane a bit like twin keels on a surfboard. It looks pretty ugly but helps prevent the damage to motor mount and props that I was experiencing. *BUT* what I felt it really needed was a folding prop. After hunting high and low for quite some time I finally concluded that small 6x4.5 folding props did not exists, and so I decided to see if I could come up with a parametric folding prop that could be 3D printed. This OpenSCAD script is the result.
