Vertex K8400 XY LinearBearing with Belt Tensioner and...

Hey,
this is a remix of NikNolte's XY-Axis Belt for UM-Clones. http://www.thingiverse.com/thing:1904762
He was so kind to give me the source file so I could costumize it for the Vertex K8400 3D Printer.

The advanteges compared to the original are:
++ GT2 Belt tensioner
++ Removable XY-Axis
++ A lot more space!

Disadvantages:
-- You have to change to GT2 Belts, T2,5 wont work. -->>http://www.thingiverse.com/thing:1857266
