Summary

This is a model of a carbon diamond lattice. It is modified from pmoews' excellent model. Changes include:

• Added scale function to the SCAD file to scale lattice to the correct size.
• Increased resolution for smoother and rounder output; this also has the effect of thickening the bonds and atoms.
• Removed (commented out) single bonds on the edges. These are fragile and kept breaking off for me when printing in plaster binder jetting. All atoms now have at least 2 bonds to the surrounding atoms.

Another advantage of removing the single bonds is that the model can now stand on a corner, creating a more visually interesting model.

Model was printed on a Z Corp ZPrinter 450 in plaster-based powder and infiltrated with pigmented epoxy.
