E3D v6 X Carriage Extended

I remixed the E3D v6 X Carriage by redkite to use 4 bearings. I was having some issues with the two bearing version being unstable.

You will need the following:
-E3D v6 Extruder, Bowden version
-4 M3 nuts
-2 M3 x 16mm bolts
-2 x M3 x 30mm bolts (25mm should work)
-4 x M3 washers
-4 x LM8UU bearings.
-8 small zip ties
