The 2 grub screws, once done up, will push the rod slightly sideways or even at a slight angle. If the grub screws were spaced at 120deg, it would probably help.

Not true. They *are* the answer.
Allow me to explain...

I have the part right in front of me, and I don't see any "wobble". If the z axis wobbles the layers become uneven. On the part, you can count the layers (4/mm) and they are all the same.
