These geometric models are primarily derivatives of the Platonic solids and their combinations.
Edge length and diameter can vary. They are all welded from steel rod and bronze welded at the vertices. They can be handled repeatedly without concern. Some are painted or plated. The basic steel rod will rust over time.
The prices vary and can be discussed if you are interested in purchasing.
Others can be fabricated on a custom basis.Combination models, such as shown in the Dimension series elsewhere on this website, 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.
