3D max model of a Menger Sponge, an Infinite fractal cube.

5 iterations of fractal cubes, with texture maps to take the illusion to 10 iterations.

A nice 3d max scene for renders, and 5 cube iterations options for 3d printing. Can be used as building blocks, by 3D printing the lower iterations, and constructing a large 3D printed Menger sponge.

Even though the highest iteration mesh has 13mil polygons, it is at an optimal number. Clean closed mesh topology.

It is a three-dimensional generalization of the one-dimensional Cantor set and two-dimensional Sierpinski carpet. It was first described by Karl Menger in 1926, in his studies of the concept of topological dimension.
