EZ3d pheonix dual extruder carriage

Here is a dual extruder carriage for the ez3d pheonix. It is specifically set up for j head extruders like the e3d hot ends and the like. It will require a mounting bracket which you can buy or make yourself. It will also require some sort of belt holder.
It is loosely based on the carriage design by Ari Robinson on the Pheonix google+ group and the bearing clamps are thanks to http://www.thingiverse.com/jonaskuehling/about.
