Tray to hold the 2 cup pet bowls from target.

You can find the bowls at target here. This tray is designed for the 2 cup bowls, you could scale it up to fit the other sizes.

It is sliced with a dovetail joint to put them together once printed. I printed without supports and it worked fine, but your bed adhesion will need to be dialed in. There is a supports version as well.
