Yes we can make them, but to get zero backlash they will need to be made at the factory, and will be a long delivery.
Also how come you dont have a floating end? you have the lower screw fixed at both ends?

16mmx5 screws with your anti backlash double nuts.

Threads are your usual M12x1, flats are 1mm deep.

I'd like 12mm ball races to slide on by hand, not tight. Other tolearances are fairly slack, shall we say .25mm
