Well, that's particularly interesting, as I wasn't aware that ArtelW had released all those old models, and I
do happen to have my own 3D printer these days (which isn't all that busy at the moment, partly because I'm still waiting for much of the resin I ordered - I have alternatives, but I don't entirely want to use them up on stuff that would be better done by the resin that hasn't arrived)
While I'm not a fan of everything in that pack, there'd certainly be something to be said for printing out an Eldar or two...

As far as the scaling, one thing I've been doing so far is exploiting the fact that I've done 3D scans of some of my models; I can load the scans into the editor and scale them based on known dimensions (usually that they have a 40mm base), and then compare the sizes there. As such, it is possible to do the comparisons pre-print, with less guesswork as far as how big they actually need to be.
EDIT: For example, for the Eldar Farseer, I can compare to a known model and say that a 1.6 scale factor would be a reasonable-ish sizing. (Possibly a
little big, so I might actually go 1.55 or so. Eldar are meant to be taller than humans, but maybe not quite so much).
With that in mind, it might be worth scanning in a known model to use as reference.
