1405 Simple X ends - Remix

I just modified Jon Lawrence great design to be able to print it on my stock simple. Just wanted to share if any one else needed it also. A tension block is needed from his thing files. I also recommend his belt wedges(http://www.thingiverse.com/thing:275874).
Design requires an additional four M3 nuts and four 20mm or longer screws to hold the parts together.
