K4-12P4(E4)

This is a Stewart Toroid. For a defintion, see the Wikipedia entry at https://en.wikipedia.org/wiki/Toroidal_polyhedron, or better still, if you can get hold of a copy, Adventures Among the Toroids, by B. M. Stewart. Unfortunately Professor Stewart did not live long enough for 3D printing to become available to make solid versions of his toroids. I am an admirer of his work and i am working on making some of his toroids available on solid form. If there is enough interest I will try to model some of his more complex toroids. This is a version suitable for display. I can make different sizes available on request. There is a simpler Stewart Toroid at https://www.shapeways.com/product/DRVUDPTK8/k3-4q3-s3?optionId=312390287&li=shops
