I was looking for a time saving way to feed the cats, instead of refilling it every day. I started a draw from scratch, but based on this model (https://makerworld.com/nl/models/1300027-stylish-auto-cat-feeder#profileId-1332179). I made it so that a stainless steel bowl would fit in it. That's safer for the cats to eat from. Easier to clean as well.
