One way is to use flexible urethane. Use a wooden or plastic dowel through the middle of the port. Block off the ends, and pour in casting urethane. After it cures, extract the dowel. The void from the dowel gives enough flexibility to withdraw the urethane plug. Now, insert the dowel back in, and use the plug to cast a mold.
