I designed this for my cat. Would also be cute for a small dog, or a big dog if you want to rescale it larger. Can also be used to hold candy or miscellaneous trinkets and jewelry.
It's tricky to print due to the curves. If you're using PETG, I recommend setting the speed slow (40-50 mm/s).
Infill: 80-100% if you want something your cat won't knock over while eating, but 20%+ if you just want a pretty bowl.
Supports: Yes. If you print as-is with supports, you'll be adding about 3-4 hours of printing time. This is what I did, but I recommend playing around with it based on what material your printing and how fast you want it printed. Printing upside down might even be better than as-is.
UPDATE: I created a modular version of this that requires NO supports. You can get that here: https://www.thingiverse.com/thing:4775983
