Sink Plug

The sink in my house ended up having its plug break due to corrosion, so I 3D printed a new cover for the sink. It's not perfect, but it gets the job done. It's a bit loose in my sink, and I'd expect it to fit in most sinks.

Best printed upside down with a water-resistant filament. I used PETG and it holds up well. I'd recommend 100% infill to prevent water infiltration into the part.
