wherein, along at least a majority of longitudinal length of the side ribs, the angular span of each of the side ribs as measured with respect to the longitudinal axis at the inner surface of the rib is the same as the angular span of each side rib as measured with respect to the longitudinal axis at the outer surface of the rib; and
wherein for at least a first point along the longitudinal axis, lines passing along the sides of the plurality of side ribs will intersect at a common point on the longitudinal axis.
