X ends for Prusa Mendel i2 Reinforced

After building my first RepRap, I noticed that the X ends were far too fragile. Beyond the fragile issue the official x end idler had a hole in the STL. This is a complete redesign I did in Sketchup 8, I have printed these so they are legit. I made sure that the STL files have been checked for continuity. These are available with and without the curl blocker skirt. I have also provided the Sketchup file so you can mod them further.
