This sculpture is composed of 20 "asterisk" structures that interlock to form a hollow sphere. The inner surface is an icosidodecahedron, surrounded by 12 pentagonal walls.
Half the size of the original Asterisk Ball; the walls are twice as thick relative to the edge length.
The shape was designed by calculating the vectors on paper, then rendered using OpenSCAD.
Diameter is 2.4 cm (0.9 in).
