You can get an engineer's template in an office supply store that
accomplishes exactly the same thing and shows the diameter/mm on each hole.  I borrowed
this idea shamelessly from Barbara Wilson-Clay -- thanks Barbara!! -- and have
one in my tote bag (Thanks Vera Bradley) -- that I take to the hospital.  It's
plastic and easily cleaned between uses.  I don't use it all that often --
only if I'm attempting to determine if a mom needs a flange that is larger than
the standard ones.
