Walkera Ladybird Prop Guards

A set of prop guards for the Walkera QR Ladybird micro quadcopter. Springy, modular (so you don't have to print the whole thing each time it breaks), and perfect to use as "training wheels" for learning to fly a quad indoors.
Hot-glue and common sense required for fastening...
Experimenting with thinner parts and L shaped cross sections for reduced weight and increased stiffness in the v3 and v4 files.
