Printrbot Simple X upgrade.

Increase your X travel to GT2 belt drive and 165mm print area while keeping the stock print plate. Larger area is capable with a custom plate.

Requirements:
- Well calibrated printer.
- Ability to print 98 mm x 98 mm (use "Orientated" files), or print 125 mm length (use standard files). I installed my Y-Axis No-Sag upgrade first, then printed parts for this one (http://www.thingiverse.com/thing:242185).
- 8mm linear rods 87 mm longer than the hole center distance on your print bed. F
