The female portion may include a concave face having substantially the same diameter D as the lower portion and a radius of curvature R. The mold may also include a cylindrical male portion having a diameter substantially equal to D. The male portion may have a central cylindrical portion with a height H extending from the lower terminus and a diameter of D-G, wherein G is the annular thickness of a spacing gap extending radially outward from the central portion. The male portion may also have a centered, convex lower face with a diameter of D-G and a radius of curvature R. The mold may also include a tubular body portion support member configured to receive a portion of the female and male portions.
