Linear Rail Z Axis for Lulzbot AO-10x and mendelmax printers

The following project will allow you to install 2 fully supported THX Linear Rails in place of the Z Axis 8MM linear rod found on the Lulzbot AO-10x series printers. It also upgrades the Z endstop for additional precision.
PREREQUISITES:

1. You must already have installed seasoe's LulzBot AO-101 Simple 60MM Height Increase Modification http://www.thingiverse.com/thing:97575
2. You need to have completed the Z-nut springs, Lower X end Clamps, and X Idler from my own existing Project: AO-Taz. http://www.thingiverse.com/thing:164054
3. an additional 40MM worth of unused X axis belt, or a new longer belt.
