ED3 V6 extruder X axis carriage for tevo tarantula (updated 01-2017)

tevo tarantula X-axis carriage to use with an ED3 V6 extruder. I reduce the distance between the fixed roller and the cam adjustable roller by 1mm to have more tightness on the 20x40 extruded X axis arm. Notice that you need to tap the threads of the m3x0.5 screws to hold the ED3 head in place.
Designed with 123D design and sliced with Simplify 3D in ABS
Enjoy!
