Slowfeeder Bowl for Cats and Dogs

Hi there, my cat Puffy eats so fast then she throws up. So i got a recommendation from her vet, she said use a slowfeeder bowl. I found it on the market but it was too expensive. So i download one of the slowfeeder that i found on thingiverse but it had too much columns that my cat couldnt able to achive to eat a bit :)))) so i designed a new one. I print it using Petg and .28 mm thickness 20% infill without supports.
If you print it let me know. Have a nice printing :)
