I wanted to use these as a mold making demo at the last prop meet up but ran into trouble and had to cancel it. The problems have been solved and I now have two molds done along with castings from both. I made seven blanks. The idea was to do a couple of multiple cavity molds but after thinking about it I decided against that. Single cavity molds will fit better into the small tank and around larger molds in the big tank. I want to make at least two more but the protoplaser comes first.
