Eventually we settled on something inspired by the shapes Henry Segerman was making on ShapeWays and Thingiverse: a stereographic projection lamp. (Funny story, he happens to have also made some … Continue reading Stereographic Projector Lamp as Wedding Gift

The technical name for the shapes would be spheres of radius 1,2,3 in the Carnot-Carathéodory metric on the real Heisenberg group induced by a hexagonal norm. It’s a mouthful. I’ll probably do another post describing how to come up with the shapes. Anyway, she’s actually already had two … Continue reading RhinoScripting for 3D CAD

I print on the lowest quality (for the fastest print) and at a pressure head of about 2cm the untreated parts didn’t leak overnight. Anything above that and … Continue reading Water, Water, Everywhere
