This is a round cup coaster design featuring a smooth ripple-ring pattern. It’s designed to be both functional and visually appealing — perfect for everyday use under mugs, cups, small bowls, or even as a base for small planters.

The model prints flat and does not require any supports or special settings. The gentle rings help keep condensation in place and provide a nice tactile detail. You can scale it slightly if needed, but it's optimized for standard drinkware.
