Unit cell of silicon carbide Alpha (2H-SiC) - STL file 

Printing can be performed by Cura suggested support structures, which in a later stage can be detached fairly easily from an actual print by a tweezer.

Parameters of the model include:

-Atom sizes in Angstrom. Relative sizes are interlocked to the whole lattice size by a single "scale" variable

-Relative coordinates of atoms are interlocked to model size and can vary by a single "scale" variable

-Bonds are created by cylinders, the diameter and length of which is interlocked to the model size, and controlled by the model "scale" variable. Cylinders are created by calling a module which accepts two vectors (positions of two bonding atoms) and two diameters (for either end of the cylinder).

-colored atoms based on type
