F3 Discovery mount for quadcopter

This mount is designed to put an [STM F3 Discovery board](http://www.st.com/web/en/catalog/tools/FM116/SC959/SS1532/PF254044) on a quadrocopter. This special mount is needed because the F3 does not have any mounting holes. It holds the board with side clips.
It accomodates to 2 different sizes of typical quadrocopter designs.
This also means that the base of this design can be used to mount a big board (e.g. quanton) onto a small copter. Just use the object from the sketchup file.
