Landing Gear for QAV400 and QAV500 Quadcopter

UPDATE: I've now included a version that can be further reinforced using a zip tie. You'll notice a small cut out where you can slide the zip tie (small ones) through.

I needed landing gear for my QAV400 so I decided to design and print some with my MakerBot Replicator 2. They turned how much better than I anticipated. I believe they'll work with the QAV500, but if anyone can verify it would be much appreciated. You can learn more about this design here:
