Yesterday I just needed a quick mesh to allow the water to drain from my pots and glasses so i quickly came up with this and it works pretty well, my wife seems to like the look of it, and it's semi modular in that you can link multiple meshes together end to end. There is also no reason you cannot scale the model to make thinner and thicker sections.  The model has small feet underneath to lift it from the draining surface.

Only a small support is needed along the linking lip and it peels away easily. 

I just used Bambu PLA Matte but I'm sure there is a better material to use that won't be affected by the water.
