X Axis holders

This is a remix of Jonaskuehlings Improved X Ends.
It is made for LM8UU, and 8mm smooth rods.
There is also a LM10UU version, but it still has 8mm holes for the X axis.
This remix will work very good with Richrap's quick fit extruder. http://www.thingiverse.com/thing:19590
The motor is placed 10mm further away from the threaded rod to align the X axis GT2 belt.
The opposite idler part is enhanced aswell. Although it was only made stronger no measurements have changed on this part
