Father Magnus Wenninger
A retired Benedictine monk, Father Wenninger is “a pioneer in the mathematical art community, whose models of polyhedra have inspired a new generation of mathematical artists”.
You can actually order some of his polyhedra, however there’s no guarantee that they’ll be exactly what you want, as they all vary. I was very surprised by this site, and found it very endearing to see him tenderly holding his polyhedra. I love polyhedra as well, so I just had to post about Father Wenniger’s beautiful work.
