This is a snap-in ring created to offer a replacement or alternative to the rubber ring found around metal pet food bowls. It’s specifically designed for bowls with an outer diameter of 150.5 - 151.5mm and a rim thickness of 2mm - 2.4mm.
I’ve included a parametric Fusion360 design that I developed, which allows you to adjust the diameter to fit your specific bowl. There’s also a parameter to control the thickness of the rim. This design comes as-is; I’ve only tested it with a narrow range of parameters, so you might need to adjust other parts to fit different bowls. 😄
