The nuts are platform-style, rather than cylindrical. https://tech.thk.com/en/products/pdfs/en_a15_228.pdf I turned a bit of square bar to produce a spigot rather like the top of the nut in that second photo, but with the top plate and spigot bolted to the complete ball nut. I had to mill a groove on the underside of the X table to clear the top of the nut --- and I would caution you not to do that, as the casting will probably change shape and bow the table. I had to have mine reground. The other axes had enough clearance, and the general method works fine.
