6 bands of 6 tori, each with a decagon cross-section, centered on the great circles with axes through the vertices of a regular icosahedron. These can be created through weaving as well. Buckminster Fuller called this as an "isometric vector matrix grid" with physical properties related to electromagnetic frequencies at the appropriate size (but with 24 bands of no thickness). These bands are equally spaced, and 1mm minimum diameter. Sets of 3 bands have a gap at the centers of the faces of the related regular icosahedron.
