The mold includes an internal surface surrounding a cavity formed therein and one or more junk slot displacements formed along at least a portion of the internal surface. The junk slot displacement includes a top edge. The blank includes an upper portion, a lower portion, and a bottom edge extending from at least a portion of the upper portion to at least a portion of the lower portion. At least a portion of the bottom edge is coupleable to at least a portion of the top edge.
