Create your own molds in a very inexpensive way, with only corn starch and silicone. The silicone caulk must be 100% silicone and clear for it to work properly.
Depending on how thick your mold is, it could take only a few minutes to about an hour to dry and be ready for casting. To cast, I use jewelry resin, but I’m sure you can also use plaster or clay. I have not yet tried making 3 dimensional molds, but I’m sure the process is not difficult, just a little more time consuming.
To do this, you might want to try separating your object into 2 or more sections with something like thin plastic sheets or cardboard. Then applying the silicon to each section, letting it dry and then separating your mold from the object. Put the mold pieces together and make sure they stay securely in place and aligned to one another by using rubber bands. Pour your casting material through a hole that you created during mold making or afterwards. Let it dry.
These instructions for 3 dimensional mold making are really just my guess and how I would go about it. If you have a better way or find an awesome video, let me know! I’d like to try it out too.
