I’m currently working on modelling the relations between the 5 Platonics and both rhombic dodecahedra.   If somebody knows of a model of the pentagonal dodeca and the regular icosa inscribed within either rhombic dodeca I would love to see it.  Modelling the the tetra, cube, and icosa within either rhombic dodeca is interesting but fairly easy but I haven’t figured out the icosa and pentagonal dodeca inside the rhombic dodeca yet.
