Spiral Arm Micro Quadcopter

I designed this quadcopter frame to be easily printed using PLA, and to fit the motors + board from a [Syma X1](http://www.amazon.com/Syma-Channel-2-4G-Quad-Copter/dp/B0096SJU3U/) quadcopter.

If you want to access the original parametric design, it is available from [Onshape](http://onshape.com) right [here](https://cad.onshape.com/documents/0f24366d6b104f858df0511f/w/69779a930f764f93a1c2d0b1/e/da1fefbe7b3148ed982e6b7e).
