About this 3D model

I Designed this because I liked the vertical axis style, but none of the current designs that I found would let you use current extruder designs. This lets you use a Gregs Wade style extruder, and most anything with the same style mount. Edit: I have redesigned the carriage bit to have holes for mounting different attachments. There is now one that will hold a Gregs Wades style extruder, and one for mounting a dremel flexible shaft to it. The top holes are spaces so a fan can be mounted to the carriage, or for extra accessory bits I have uploaded the SolidWorks2012 files below, as well as the assembly and the support files as a rar.
