Faujasite, from the Zeolite family, an aluminosilicate forming sodalite cages which are connected through hexagonal prisms. It is used in cracking, hydrocracking and as CO2 absorber for air purification. I modeled it in Avogadro and then I used a Python script that I wrote by myself in order to import it into Blender. It's ready for 3D print, so feel free to download it.
