You can of course adapt the font size instead but as it's just stickers
the above is probably good enough, but you can do this:
\begingroup
\doloop {
\setbox\scratchbox\hbox\bgroup\framed
[align={flushleft},strut=no]
{\startlines[before=,after=]
\getbuffer[address]
\stoplines}
\egroup
\ifdim\wd\scratchbox>3cm
\advance\glyphscale by -50
\else
\box\scratchbox
\exitloop
\fi
}
\endgroup
to get more consistent stepwise scaling or even this:
\begingroup
\doloop {
\setbox\scratchbox\hbox\bgroup\framed
[align={flushleft},strut=no]
{\startlines[before=,after=]
\getbuffer[address]
\stoplines}
\egroup
\ifdim\wd\scratchbox>3cm
\advance\glyphxscale by -50
\else
\framed
[align={flushleft},strut=no,width=3cm]
{\startlines[before=,after=]
\getbuffer[address]
\stoplines}
\exitloop
\fi
}
\endgroup
which is what i might choose eventually (i'll add it to the test suite)

Did you try \framedtext instead of \framed? (I didn’t test.)
