Johnson polyhedra have faces composed of regular polygons: triangles, squares, pentagons,hexagons, octagons and decagons. There are only 92 such polyhedra. Instructions for making paper models are available, but with stl files one could print more durable examples.
I recently came across the netlib library of polyhedra at
http://netlib.sandia.gov/polyhedra/
which includes the Johnson polyhedra. I was pleased to see that it would be easy to convert the files to openSCAD polyhedron comands. Polyhedron commands are
a compact way of describing a polyhedron and, when executed, output an stl file.
I wrote a fortran program to convert the files; however a few files had errors. I had corrected most errors with openSCAD's unusual, but marvelous, "thrown together" mode when I was informed that the errors had already been noticed and corrected by George Hart
