Pieces of wood or hockey pucks. Can paint the wood and/or add black felt to cover it. I've also used big rubber stoppers but those are hard to find anymore (I had a supply ordered from a lab supply company many years ago).

Wondering if there's something metal. Like stainless steel disc, but thick.
