600-Cell Central Rings.stl

This is a three-dimensional shadow of selected cells of the four-dimensional shape called the “600-cell.”

See here for video: https://youtu.be/IhW48X29e0g 

The 600-cell is one of six regular convex four-dimensional shapes. It is composed of 600 tetrahedral cells.

The full 600-cell is so ridiculously complex that it nearly impossible to see or understand in its entirety, so it is helpful to view it in parts.

If you look closely at this selection of cells, you can see how it is composed of nine interlocking rings connected by “struts.”  In the full 600-cell, these small “struts” are in fact part of complete rings. This gives some idea of how large and complex the full shape would be.

This model is designed for resin printing.

Weaire-Phelan Tumbler

This “Weaire-Phelan Tumbler” is part of a set of three tableware pieces inspired by the Weaire-Phelan structure, the most mathematically efficient way for equal-volume bubbles to fit together to make foam. See here for video: https://youtu.be/f4YIuS_-hSE

This piece could be used as a vase or pencil holder.

The Weaire-Phelan structure is made up of two pentagonal dodecahedra (12-sided) and six tetrakaidecahedra (14-sided) that form a translation unit with a lattice periodicity which is simple cubic. In crystallography, this structure is also known as the A15 Frank-Kasper phase.

There is a good introduction to the “Weaire–Phelan structure” here: http://www.steelpillow.com/polyhedra/wp/wp.html

Ultimate Pasta

This is the ultimate piece of pasta. If you have a Pasta Printer you could print it for World Pasta Day on October 25 or US National Pasta Day on October 17.

This playful sculpture is derived from a matrix of Kelvin polyhedra, a fourteen-sided polyhedron with 6 squares and 8 hexagons. A triagonal piece of pasta is stuck on to each hexagonal face. This structure is also known as 8-srs. Yum.

النرد الأبجدية العربية
A unique non-Isohedral die with every letter of the Arabic alphabet on its faces.
Note that this die is based on a tetrahedral 28-hedron, which has three types of faces, however the die is still nearly fair because the areas of the faces were balanced in such a way that they have practically the same probability of being landed on.

Preveiously I designed a trapezohedral version of this die.
