I found this waterproof container that says, "fresh-r-matic". I think it might be one of those waterproof match containers. Anyway, an 18650 fits perfectly inside of it diameter wise but it's too long. Is a 123 battery the same diameter? Will two 123 be shorter than one 18650? My next step will be to find a machinist that can cut the top off and make a cap out of it.
