Gregor not sure you have done enough checking etc to make sure things will fit correctly.
I know for fact how you have it designed now the ballscrew won't fit on the gantry without lot of messing about. You'll also get clashes from Ballnut brackets etc which will result in loss of travel.

While my design works great there's very little spare room so if your going to copy how I build them you need to follow exactly of at least check for clashes etc. This means more detailed Cad model with accurate models of parts used.

How you have it now won't work very well. These might help explain better.
