For those interested in such things, here is a page that shows
the "3D analogue" version of the "missing square puzzle" that
I was asking about:
(complete with plans for making your own).

I.e. you "completely" fill a box using either N or N-1 of the
accompanying pieces
(in short, it relies on the same fundamental trick as the planar puzzle):
N
(P.S. Again, for those really interested:
While searching for this, I came across a website
listing a truly amazing set of various puzzles, etc:
