If DIY is not a problem, you might consider doing something in a C-Beam format except built around V-Slot linear actuators built with Nema 17 end...
You might try tightening the nut a bit more. I've had to really crank down a few to take out the slack. You may also have a bad bearing....
A constant force spring would be much cheaper. Example - Source - Another Source
Oh, I follow the principles I just think the level of precision required would be difficult for the average person to achieve especially with the...
If you're flexing about the nut block something is seriously wrong. And a more rigid threaded rod is not the solution. Start by giving the...
You might start by just switching out your short spacer blocks with a pair of @Chris Laidlaw's extended version. The extra set of wheels that was...

There are plenty of online calculators. (example) Use E = 10000 ksi and c = half of section depth. The problem is getting the I value. Someone...

The official position is section depth + 19.8 mm for the center to center distance of the bolt holes. In the real world however I find the...
Steel doesn't extrude. You can however fasten V-slot to steel framing as needed.
The only other reason might be the majority of the predrilled plates are set up for the larger wheel.
Besides, at the very least the router is sucking all that debris back through it's airflow system. Can't be good for it.
You may be able to achieve the same thing just by removing the nut and wedging a stiff spring inside the existing anti-backlash nut block.
