Dodecahedron pendant

thingiverse

This pendant is inspired by Olafur Eliasson's large 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 sticks and cubes regular icosahedron. Its diameter measures around 300 mm. This design illustrates that the pentagon dodecahedron and the icosahedron are dual polyhedra, with faces matching corners in each 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, matching the diameter of sticks. I made the sticks from 6-6.5 mm Ø wooden flower sticks. I drew a regular pentagon with side length 85 mm, added glueing flaps to it, and printed 12 copies on regular printer paper. After cutting out the pentagons, I glued them together using the flaps turned inwards. After several attempts, I settled on stick lengths of 130 mm, which makes the inner dodecahedron touch but not press on sticks of the outer icosahedron. For building, I placed lower and upper parts of the icosahedron on top of a round bowl. I hope this information helps build something similar. Farum, Denmark, November 18th, 2019
