I made this pet food bowl insert because my dog is a pig and eats really fast. They make bowls for this reason, but why buy when you can DIY. 

Easy to wash. I suggest only using food safe filaments. Hand wash with warm (not hot) water and soap.

This insert was designed for a 4.5in bowl. Feel free to scale it to the bowl of your needs.

Files include a simple small bowl too.

Enjoy!
