X Axis Motor support for P3 Steel with leadscrew

This is simply another version of the reprap X-Axis for the Prusa i3 Steel,
(I'm not sure, but I think original is from Xoan Sampaino https://www.thingiverse.com/xoan/about )

I redo it on freecad and it has some parametrics, mainly the separation between leadscrew and steel rod (in the STL are 17mm)

Also diameter of the linear bearing is a bit small and parametric, because I use igus plastic bearing and they are a bit less in diameter.
