i3 X-carriage for GT2 belt and more Z

This is an X-carriage for Prusa i3 printer, made with SolidWorks 2013. I designed it to fit GT2 properly, unlike the original design does. It also has extruder mount point above the belt. That allows the extruder to travel higher, and gives more Z travel. I tried to keep the original look.
The mount holes for extruder are 30 mm apart, and the design accommodates 3 LM8UU or LM10UU bearings. Other types upon request.
