reprappro x-Axis 1/4 rod for USA

OK here is another new version of the X axis for reprappro. The difference is not only is the IM8UU being used in the X Axis but since I live in the “third world” when it comes to measurement - AKA the “US of A” I can't get metric parts easily like the M5 threaded rod. It turns out the best I can do at least going to a “Home Depot” is to get a ¼ rod thread so that is now what I am giving anyone that wants it. I will provide calculations for the steppers when I do them but until then here is a IM8UU based X axis with ¼ rod for Xaxis.
