I'm currently in a rabbit hole looking for material compositions and stumbled onto google patent search. In 2016 Soma International, a toy manufacturer, put a patent in for a rock tumbler. I cant find if they actually made it or not, but the patent is interesting to look at none-the-less. It's like the nested Russian doll of tumbler barrels. Inner barrel fits into middle barrel, then middle barrel fits into an outer barrel, with insulation in between. Too many moving parts, and kind of ridiculous IMO. patents.google.com/patent/US9421664B1/en

Seems like a lot of complicated stuff to get a quiet tumble, an interesting read though. It does say Status: expired-fee related, so probably never manufactured. Thanks for putting it up.
