Summary

A Fractal Spiraling Network Which Corresponds to Hyperbolic Space

has loads of free 3D printing resources (design apps & stls) on it.
The structure forms fractal, highly clustered parts around the perimeter, with bridges over the middle which make travel easy. It can be thought of as the net of a self intersecting surface.
About the thing.. The shape was grown from tiny rules, starting from a cube. The network cannot be drawn on a sphere without edges crossing. It can be thought of as the net of a self-intersecting surface. If one keeps growing the surface, it basically makes hyperbolic space. The number of hops between a randomly chosen pair vertices is surprisingly small.It has this `small world' property just like social networks, protein interaction networks, the internet, etc.

Version 3 looks better, but version 5 is easier to print because it has a flat base.
