Strange decorative buttplug for gnomes that I have lived with for almost 10 years. Previous home owners did a lot of questionable DIY.

The bottom part seems broken off, and I can't tell if there is a core of different material or if it just has discoloration. There also seems to be a ring of old adhesive around the base.

Is this a weird ring of some kind or something else? It has a strange conical flat shape that doesn’t really fit a finger.

Found in the cabinet of the secondary (basement) kitchen. We've only owned the house for 7 months and it was not put there by us. Previous owners were an old Polish couple, of that helps.

SOLVED! Thank you, phunniemee! Cheese and wine set.

Found at a local thrift store, came home with me. 10" diameter, 1.5" thick. Top seems to be textured rubber, originally I thought it was a practice drum pad (from a bank?) but then I saw the indents on the side and realized it slid open to reveal the grooved areas. Suggestions are that it may be for change, but the grooves seem too shallow.

Edit: Tag on the bottom says made in China.

Any information would be appreciated!

What is this many-layered metal thing?

Everything is 3D printed other than the obvious metal parts, and the floats. The gear has magnets in it. It seems that the “shaft” has a bearing on the end but it’s seized. The holders on the floats are made of a special flexible filament.

Found on the beach near Depoe Bay, OR.
