Dreamcatcher Micro Quadcopter

## Why
I loved the idea of the [Ultimate Micro Quad](http://www.thingiverse.com/thing:431290) (the original dreamcatcher as far as I can tell), and the [customizable variant](http://www.thingiverse.com/thing:931685) by driggers.

I wanted a customizable version (eg for different motor and board dimensions), but as much as I love the *idea* of OpenSCAD, I don't love the *experience* of using OpenSCAD to modify frame variables, especially in situations where heavy modification is necessary.
