Single E3D Lite6 HotEnd X Carriage for Zonestar Prusa I3

Hi,
I made this X carriage for my Zonestar Prusa I3 (P802-Y) as the original one was to flexible and the HotEnd mount was to loose.
It is based on Stevans design, which can be found here: http://www.thingiverse.com/thing:871433
To rebuild it you will also need
X_Single_Extr.stl and X_clamp_1_Extr.stl from his design, these parts were scaled up by a factor of 1.007.
The X plate is designed to hold two SCS8UU or preferable SCS8LUU bearing blocks. Currently I'm using the shorter one
