TiO2 (anatase) Ball and stick model

thingiverse

It's a 3D model of a titanium dioxide crystal lattice with an anatase structure (https://en.wikipedia.org/wiki/Anatase). The model was created using detailed measurements from the Springer Materials database (https://materials.springer.com/isp/crystallographic/docs/sd_1925693), including all angles, ionic radii and interatomic distances. It features titanium atoms (larger spheres) and oxygen atoms (smaller spheres), along with chemical bonds connecting them (rods). Neodymium magnet nodes are planned in the atoms: a 5x5 grid in titanium atoms and a 3x5 grid in oxygen atoms. Smaller channels for iron wire or rod scraps, 5 mm thick and 3 mm in diameter, will be included in the links. The entire model is surprisingly stable without magnets, relying solely on friction to hold it together. To ensure stability, you can use CA glue to secure the model permanently. Due to a printing issue with my budget-friendly printer, I had to create self-made supports for the models of atoms and bonds, both with and without support.
