Cobblebot E3D Chimera/Cyclops Mount

This mount is meant to completely replace the existing (on my printer) y-axis carriage on the Cobblebot printer and allow for the Chimera/Cyclops to mount. I got the basic idea for the mount from Repraph (http://www.thingiverse.com/thing:603881). This is a work in progress so any suggestions are welcome! Within a couple days I should have the design finalized and ready to go.
