Icosahedral Containers

Here are 3 containers based on the icosahedron. They were constructed by using the faces of an icosahedron as the bases for trigonal pyramids - one set of 20 pointing into the icosahedron, a second set pointing away from the icosahedron. The containers were constructed by adding pyramids to, or subtracting pyramids from, the icosahedron. OpenSCAD code is included.
