Tyro69 propeller guard

I was going through propellers pretty quick learning to fly my new toy, so I made this propeller guard. There are a couple other designs already, but they all mount to the motor arm. Their geometry make them hard to 3D print. I designed this propeller guard to mount to the avionics stack. It makes it very easy to print and relatively strong.

It isn't perfect by any means, but it's way better than no prop guard. If it print it again, I would probably add another 0.5-1mm of thickness to the 1mm thick mount portion, in order to make it a bit stiffer. It's OpenSCAD, so knock yourself out!

Cura estimated the mass to be 5g of PLA.
