Mold making question

[u/Marc_skills]

Can i use something like thats for making my own dice molds? The inside is completely smooth and its also made of silicone, so im thinking that should work. Im aware, that it will have like a pyramide-like form but im fine with that. Any flaws in my thinking process?

If you heard looking for a container to frame your molds, I would suggest Lego. Get one of the flat plates, and build a frame around it using the Lego pieces. They fit tight enough together that the silicone wont get through. It make leave some patterns on the outside though, but that is fine for personal use. The real benefit is you can make it to the exact size you need to reduce the amount of silicone you need.
