Fancy molds with high tolerances require multiple iterations of making molds then destroying them. You can also find that parts are not able to be shot, usually before, but sometimes after making the mold. The texturing and cuts are expensive and difficult as well. If they were going for Apple-level tolerances, they're walking into a minefield.
