NaCl unit cells

This is a model of an NaCl unit cell in the scale 1: 10-9. Both unit cells fit perfect in the ionic lattice model: https://www.thingiverse.com/thing:3887597
In the new version 2 of the lattice the spheres overlap, are more rounded and cut off at the bottom.

This model and other educational examples can be found on the Erasmus + project website: make in class: https://www.makeinclass.eu or the website of the Gymnasium Neubiberg https://www.gymnasium-neubiberg.de
