E3D v6 carriage for Ultimaker 2

**Update** e3d just released the official models for this design. They can be found here: http://www.thingiverse.com/thing:1934309

I saw that E3D had just released a E3D Extrusion Upgrade Kit for Ultimakers. I already have a spare V6 that I plan on installing into a UM2 Clone in the works. I loved the idea and attempted to use the pictures and some specs to recreate it. I haven't printed it yet, so if you happen to get around to it before I do, let me know if any changes need to be made.
