ABSTRACT:
A three-dimensional grid includes a planar base portion and a plurality of protrusions. The protrusions are spaced about and project substantially perpendicular from the base portion. The projections are convexly curved and are integrally formed with the base portion by slitting and shrinking a single sheet of plastic. Additional layers of materials may be alternatively attached to either or both of the planar base portion and protrusions.
