Yes.  Without question.  It would be replacing a "credit-card toolkit"
which is about 7 mm thick; I don't really need that any more, as I
now carry a Gerber multitool on my belt.

Building one was always an option, of course, but not my favorite.  I have
no doubt that I could manage it, but It may (will) be thicker than I'd like.
The real problem thickness-wise is the need to measure AC.  If it were
only for DC, I'd leave the PCB mostly bare or put some token covering on
it.  For AC, I REALLY need to put a good, thick case there to keep my
pinkies safe.

Probably just thin, short wires.  Say, 30 gauge wire wrap?
