[Tex/LaTex] A bold plus symbol in math mode

boldmath-modesymbols

I'd like to use a different + symbol in addition to + in math mode, preferably one which is just bolder than the standard one.

I'm currently using \pmb{+} from the amsbsy package, but it's a bit too lean for my taste, and it looks a bit pointy to the ends.

I am aware of \ding{58} from the pifont package, as well as \Plus from bbding, both of which seem to be non-math mode symbols, and look really bad next to math symbols.

Am I missing some other option to produce a bold +, apart from drawing the symbol myself?

You can us bm to access the bold + from the font used for \boldmath (which in the standard setup is the font used for \bfseries in text.

enter image description here

\documentclass{article}
\usepackage{bm}

\begin{document}
\showoutput
$1 + 2 \bm{+} 3$
\end{document}
