Luna (a Pomeranian) eats every meal like it will be her last. Unfortunately this has some side-effects, like her vomiting after meals, sometimes even hours later.
There are certainly other "let them slow down while eating" bowls out there, in this case we decided to treat Luna like a guneia pig and watch her while she went through various iterations of different bowl designs until we finally settled on this one.
Since we have multiples, this was designed to be loosely stackable. For us printing in PETG is preferable since PLA/PLA+/PLA Tough does not survive the dishwasher.
Notes on the models: In addition to the .stl models and the .3mf files, I'm also sharing the original .scad model file - this requires BOSL2.
