I will be using 1605 doublenut ball screws for X and Y and a custom machined 2005 on the Z.

.

Just bear in mind that you'll need to grind off any flanges, there's about 36mm of space, I've used 1605 ballscrews and the nut flanges were 40mm across. I ended up grinding 2mm off top/bottom on the Y axis and 4mm off the top on the X axis, centre height on X ended up at 21mm (22.5mm originally).

Also, check the length of your double ballnuts on the y axis: you can probably fit about 23cm of screw in there before it hits the column, so if your nut is 10cm long you'll restrict your travel to 13cm.
