Pen Holder Voronoi

The design of this pen holder was inspired by the fascinating Voronoi diagrams. We find this kind of structure at different scales everywhere in nature, such as spots on the body of a giraffe, soap bubbles in a glass, the leaves of trees and other plant or animal cells (with a microscope), fields of dried mud, and so on... These structures are not only beautiful, they are also very efficient and strong.
