Henry Segerman - Geared Mechanisms - G4G14 Apr 2022

We will present various 3D printed geared mechanisms. Two of these are octahedral and cuboctahedral variants of Buckminster Fuller's Jitterbug mechanism. Here the gears help stabilize the mechanism and prevent jamming. In the cuboctahedral case, the added gears rotate non-linearly, so requ

How to Construct a Dodecahedron

How the greeks constructed the Dodecahedron. Euclids Elements Book 13, Proposition 17. In geometry, a dodecahedron is any polyhedron with twelve flat faces. The most familiar dodecahedron is the regular dodecahedron with regular pentagons as faces, which is a Platonic solid. A regular dode

Geared Cuboctahedral Jitterbug

3d print available at http://shpws.me/R8NY. This variant jitterbug mechanism is based on the cuboctahedron, expanding to become a rhombicuboctahedron. For this mechanism the rotation rates of the triangular and square parts are not linearly related to each other. This means that our gear
