original Prusa I3+ Z axis ends for 8mm leadscrew

I'm building my first P3steel and wanted to integrate Z axis 8 mm lead screws. One of the requirement was to use original distance between 8mm smooth rod and 8mm leadscrew so I remodeled original prusa i3+ xends.

Warning: Not yet test printed this is still work in progress!
