Dodecahedron pendant

thingiverse

This pentagon pendant is inspired by Olafur Eliasson's much larger pendant named OE Quasi Light, launched by Louis Poulsen of Denmark in the spring of 2019. It consists of a paper regular pentagon dodecahedron surrounded by a sticks and cubes regular icosahedron. Its diameter is around 300 mm. It illustrates that the pentagon dodecahedron and the icosahedron are dual polyhedra, as the faces of the one match the corners of the other. The shown prototype was built from 12 plastic 3D printed dodecahedra with holes, 30 wooden sticks and a paper dodecahedron. The 3D printed dodecahedra were designed using Autodesk Fusion 360. A dodecahedron tutorial is available on YouTube. The prototype dodecahedra have a distance between parallel faces of 30 mm. Holes in the center of five faces have a depth of 10 mm. The hole diameter must match the diameter of the sticks. I made the sticks from 6-6.5 mm Ø wooden flower sticks. I made the inner dodecahedron by drawing a regular pentagon with side length 85 mm, adding glueing flaps to it and printing 12 copies of it on regular printer paper. After cutting out the pentagons, I glued them together using the flaps turned inwards. After several attempts, I ended up with a stick length of 130 mm, which makes the inner dodecahedron touch but not press on the sticks of the outer icosahedron. For building, I placed the lower and upper part of the icosahedron on top of a round bowl. I hope that somebody can use this information to build something similar.
