This bowl fits my cat's elevated food plate that I can put water in to keep ants away from the cat's food. I printed the bowl with eSun PLA+ with the usual fast settings in PrusaSlicer, and I varnished the inside of the bowl with waterproofing acrylic varnish.
The elevated cat plate this works with can be found on Amazon (link https://amzn.to/3jkiCgL). It's a super simple print and works quite well (even after months of use).
