Ah! Ok. That does make a lot more sense. You know me -- always
approaching it from the "How the hell am I going to build THIS?" point
of view. :)

        Well, having no idea what this thing looks like - could you invert the
model and build the core itself? The core could be used literally as a
core for molding. Pour RTV silicon rubber around it and then extract
the core.
        Another approach, use a cutting plane across the completed model --
assuming the interior geometry would allow it -- and then generate the
two halves. Use them as patterns to generate molds, and then use the
molds to cast a transparent material. Assemble the two pieces, and you
have your solid mathematical object.
