The best triply periodic minimal surface ever! I put a bigger one here.

A Klein bottle. Warning: this Klein bottle does not open beers, it just looks cute.  The Klein Bottle Opener is here on Shapeways or here on...

If M.C. Escher had owned fidget toys, he would have worn "One ring to rule the ball" as a pendant. A single, continuous line contains a small ball...

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...

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 re...

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...
