Wine Bottle Coaster

This is a decorative coaster for a wine bottle. It's purpose is to be ornamental and to prevent red wine stains on surfaces.

I created it in FreeCAD and printed it with a Prusa MK4S (with supports). There are two parts:

1. The Frame - This is the base, the side panels, and the top ring. I printed it sitting upright with PLA and switched filament colors at different layers.
2. The Saucer - This is the flexible part at the bottom with a groove around it, so that it fits into the frame. I printed this with TPU so that it is flexible and so that it will prevent the bottle and coaster from sliding or from making scraping noises when moving it.
