The tetrahedron, octahedron, hexahedron (cube), dodecahedron and icosahedron are the only perfect solid geometric figures that exist. These models are constructed of 1/8 inch (3.175 mm) diameter steel rod. All the edges are 3 inches (76.2 mm) long. They are bronze welded at the vertices and are very strong. They can be handled repeatedly without concern. There are no sharp edges. I have made many sets for classrooms and hands-on museums. I guarantee the construction for the rest of this millenium.
Steel models make excellent soap frames. They can be fabricated with steel handles for an additional charge. This makes for easier use by students in classrooms or museums. Security cables can be included also.
For information on soap films, see the article "How to Build a Tetrahedron". The soap film can be made to fluoresce in black light. Email me and I'll tell you how. The navigation links have an email option.
Other geometric models can be fabricated on a custom basis.
Combination models, such as shown in the Dimension series, Archimedian solids and snubs can also be made. If you wish a particular item, one can be created just for you. Please feel free to email me and we can discuss it at no cost or obligation.
