Another projection of the 4-dimensional hypercube, this one close to vertex-centered. I love the shape of its hull: almost a rhombic dodecahedron,...

A theorem walks into a bar... The Klein Bottle is a mathematical joke: a surface with only one side. This one feels just right in your hand and ope...

There are six regular convex polytopes in 4D, which are analogous to the five Platonic solids in 3D. This is the fifth, the hyperdodecahedron, a r...

A 3-dimensional version of the Hilbert space filling curve. As shown in the photos, if printed in one of the "Strong & Flexible" plastics, it can b...

A pendant for metal printing.  I think this may be the most adorable thing ever.

This is a model of the woodcut picture made by M.C. Escher in 1965 called 'Knots".It has since then been a challenge for 3d modelers and mathematic...

A smaller version of Triple Gear is available here. A baseplate and axle for using a motor to move the triple gear is available here. Also see 15 c...

There are six regular convex polytopes in 4D, which are analogous to the five Platonic solids in 3D. This is the third, the hypercube or tesserac...

A delightful surface: the gyroid put through a simple inverse transformation. It's ellipsoidal on the outside, and there is a sphere taken out of ...

A surprising arrangement of figures to create a mathematical form. Please note that you must order TWO SETS to create the cube – each set includ...

A self-referential tessellation of the sphere.This is a little delicate as the lines are 1.5mm thick, but it seems sturdy enough.

The sizing for this ring is between a 7 and an 8

This steampunk style knotted cog was procedurally generated using 3-dimensional spherical geometry, then stereographically projected into our (most...

This is one of Escher's tesselating fishes in 3D. Several of these fishes can be grouped together, so that they form a never ending pattern.See als...

The same as this model on bathsheba.com: here it is in some other materials. Bigger version here.
