Tevo Tarantula Dual E3d V6 X carriage

After I used the existing dual e3d v6 design, I quickly realized I needed the ability to calibrate the hot ends Z offsets, while remaining accurate in the X-Y position.
This is my 2nd design for an x carriage that allows such flexability
This design locks the XY position with a V slot (using a single M4 Screw and nut in the back of the V).
Z adjustment is done by loosening the M4 screw and relocating the hot end at the desired height.
