Before I go off and re-invent the nut, does the BOSL2 library provide a module for modelling metric square nuts? It appears that metric_nut() only provides hex nuts. I very much like the way that square nuts are used in the Prusa 3D printer and would like to use that method myself. Thanks!

There is presently no direct support for square nuts. Write it and we'll add it. The main nontrivial thing missing, I think, is the table of nut sizes. One thing to be aware of is that right now BOSL2 has two redundant systems for making screws. Probably metric_screws.scad will go away because it's less general than screws.scad. But at the moment, screws.scad doesn't know about nut dimensions at all.

Adrian, Well, since Amazon has promised that my order of assorted square nuts is to arrive this Friday, I may just take that challenge. The only issue is that I know absolutely nothing about GitHub. Is there a tutorial for the workflow of contributing updates? Thanks!

metric square nuts, where a standard is quoted is are often to din 562  (some dimensions here (https://fullerfasteners.com/tech/din-562-specifications/) I've no idea if Prusa's nuts are to that standard. Of course, you could always add aero nuts, T nuts and Nylocs, etc. (and the equivalent for Ansi, too.)
