Lid for CatIt Design Senses feeder.
I noticed that our cats tended to eat just over the top opening, bypassing all the harder parts. This lid is spaced so that it's easy to slide in place, but it's tight enough so that cats can't just pry it off.
For the imprint, I used the paw-stamp from https://www.thingiverse.com/thing:67737
Printed with generic PLA. The collar is angled so that no supports are needed, so you can print it with the paw-side up.
