The Play-Do can be used to make molds also, haven't needed to yet but there is no reason it will not work. I am not sure but I think it will not shrink when it dries out and hardens, I will have to try that some day and find out.
If I remember it can be made out of 50% flour and 50% salt, with enough water to get that puttylike consistency.
Next time I pass an air conditioning duct place I have been planning to get some 22 gauge, (or 18 gauge), duct metal to use for a magnetic base in my laser. It is tin plated steel so it should work well and not rust and if you find the right place it is incredibly cheap.
