My Variation on the Voxel Ox

This is my variation on the Voxel Ox (http://www.openbuilds.com/builds/voxel-ox-extendable-3d-printer-and-cnc-platform.2418/). I liked their concept of an easily extendable/expandable printer with rigid connections.

The modifications I made are pretty much only to suit standard length parts from Open Builds.
1) The X-Gantry is attached to the back of the vertical-travel Z plates via one corner connector each
2) The top brace is a sideways 20x40 (the 40 in the up/down direction) with motors
