3D printers are an endless source of usefulness. My ancient bathroom sink drain plug lifting mechanism broke such that it was always stopping the drain. I couldn’t leave the plug out because if you drop something in the sink, down the drain it goes. So I made a plastic version sized slightly different than the original so it would not stop water from draining.
