The truncated tetrahedron has four triangular faces and four hexagonal
faces. There are 12 vertices at which one trianglar and two hexagonal
faces meet. It has 18 edges. Six of these edges are hexagon (he--he)
modules, and the remaining 12 are triangle/hexagon hybrid
(tr--he) modules.
You can color this
with three colors as follows: Arrange the he--he modules like they
are the edges of a tetrahedron. Then add the tr--he modules so that
all triangles have edges of each color. You can do this so that each
hexagon has no adjacent edges of the same color, or so that hexagon
edges all come in pairs of the same color.

These are very stable polyhedrons.
