The diamond cubic crystal structure is a repeating pattern of 8 atoms that certain materials may adopt as they solidify. However the object has than 8 atoms because some atoms are shared among adjacent crystal units (so they count as a fraction). When composed of two different atom types, the resulting crystal is called "blende" (like Sphalerite Zn and S)
See wikipedia description for more details: https://en.wikipedia.org/wiki/Diamond_cubic
The structure is also used as model for the "Wallonium" artistic artefact with top 5 atoms of the crystal colored in black (see http://wallonium.be ) So you can build you own wallonium from this crystal.
Can be printed in two ways:
1) in two halves with some support. Print the same piece twice (because symetric), remove support and then glue together
2) in individual pieces easy to assemble:
