Not unlike when I look in the mirror.

Sure. Slip castings. A cube has 12 edges. make a model with six as so:

you can easily make a muliple-cavity slip mold allow casting many
halves at once. Start with a single cavity mold and make as many copies
as cavities you want. Then use the perfect copies to make the
multiple-cavity mold. Pour your slip, wait for it to set up a bit, and
finally remove. Then use slip to "weld" two halves together, let dry to
leather-hard stage and fire. Be certain to use strong negative draft
angles so facilitate easy release from the mold and to avoid cracking of
the parts as they shrink in the cavity during dryout.
Plaster slip molds are pretty easy to make. This one should be either
two- or three-part. I think two should do it, but without having it in
front of me in 3D, I cannot be certain.
