Quadcopter "Crossfire Mini" for Small Printers (15x15)

I love the amazing work done by MikeyB on designing an open source quadcopter frame, however it was designed for a 20x20 cm build platform which not all printers have. I for my self have a printrbot LC which has a **build platform of 15x15cm**, so I shrunk his design to fit on such a space. This is the result: the "Crossfire Mini".

This thing only contains the *modified* files. Please also see the original quadcopter "Crossfire" by MikeyB for the rest of the parts, more images, recommendation
