A second hoop having a substantially constant second diameter, wherein the second diameter is less than the first diameter; c. A third hoop having a substantially constant third diameter, wherein the third diameter is less than the second diameter; d. A first circular row comprising a plurality of substantially isosceles triangles wherein each isosceles triangle comprises two spiral ribs and a hoop rib, and wherein the spiral ribs extend between the first hoop and the second hoop, and the hoop rib comprises a length of either the first hoop or the second hoop; e. A second circular row comprising a plurality of substantially isosceles triangles wherein each isosceles triangle comprises two spiral ribs and a hoop rib, wherein the spiral ribs extend between the second hoop and the third hoop, wherein the hoop rib comprises a length of either the second hoop or the third hoop, and wherein every other isosceles triangle disposed in the second circular row shares a hoop rib with one isosceles triangle disposed in the first circular row; and f. Wherein the isosceles triangles of the first circular row and the isosceles triangles of the second circular row are substantially co-planar.
