Voronoi pen

thingiverse

As a biomedical engineer, I am fascinated by the Voronoi structure, as it resembles the structure of trabecular bone. I designed the outer structure of the pen, so it fits one very common, yet fine pen filling. Get the Cristal Original pens from Bic, take out the filling and push it into the 3D printed pen body. The original cap also fits the 3D printed pen (maybe at some point I'll design a Voronoi cap too...). The size of the STL is quite big and I believe there are many double triangles, but it prints fine, so I couldn't be bothered with fixing it. Some kind of shrinkwrap should do the trick normally. (Feel free to fix it and share it).
