I had problems finding them as well, but found that Lowes had a bunch. 5/16 well nut should pop right up.

Yes, I read about the wellnut fix. For some reason they're hard to come by in my area so while the one I ordered online gets here I decided to work on this one, sort of as a side project. Also to get a better on understanding on how different versions affect printing quality.

Thank you for the suggestions.

It can help with wobble if it lets the nut slide in X and Y without any slop in Z.  I don't know if that is the case with this.  It relies on a tight press fit of the nut rather than trapping it, which would be better.

Yes I know, I'm working on two slots to allow it to slide in X and Y.

Still confused about this, it's called "anti-backlash nut" because it's a specialized nut, or just because it's used here for anti-backlash purpose?

Anti-backlash nuts exists, specially for CNCs I believe. In this case it ia just a regular one.

I'm still testing but I believe it fixed z wobble problems by 50-60% at least for my SD3. Next step is to add the firmware fix, if anyone can facilitate me instructions for the firmware fix I would be grateful.

Please print, test and let me know how it goes. Suggestions are always welcome.
