The double pyramid shape is also known as an octahedron and is one of
the Platonic solids.

Here's another way to make one using "cylinders".
for (k = [0,1]) mirror([0,0,k])
 cylinder(r1=1,r2=0,h=1, $fn=4);

Another alternative would be to construct one from points and faces
using the polyhedron module.
