QU-BD TwoUp Upgrade

This is another attempt to upgrade on the cheap the QU-BD. In this, a remix of my first attempt http://www.thingiverse.com/thing:1101105 and/or adaptation of http://www.thingiverse.com/thing:1058861 and http://www.thingiverse.com/thing:177256 to use most of the electronics and hardware from the QU-BD 1/2Up. The extra hardware are some nuts and bolts #6 from my local hardware store, and an anUbis or E3D v6 Bowden, this keeps the inversion to minimum and you don't need to order online any othe
