Johnson Polyhedron-Dual Compounds

Here are the 92 Johnson Polyhedron-Dual Compounds. The openSCAD files are collected in Johnson_Compounds_Scad.zip and a selection of the stl files is in Johnson_Compounds_Stl.zip.

The dual stl files described in thing:32101 were converted to polyhedron commands to speed computation.

The Johnson polyhedra are varied, some are not very symmetric, and in fact some of the compounds are ugly. However 8 of the Johnson polyhedra have vertices
which are equidistant from the origin, (J27, J34, J37, J72, J73, J74, J75, and J80), and their compounds resemble the Archimedean-Catalan compounds.

Elongated Johnson polyhedral compounds often have interesting belts or end caps. Attractive ones are: J35, J38, J42, J43, J46, and J48. The truncated cubes and dodecahedrons, J66, J67, J68, and J69 are fairly attractive and should make nice 2 color prints. The rhombicosidodecahedrons, J76, J77, J78, and J79 are interesting compounds with a single downward spike.
