Slow Feeder Dog Bowl - For Flat-faced Dogs

I purchased a slow-feeder dog bowl to keep my dog from inhaling his food, but because he's a French Bulldog with a flat face he wasn't able to get food out of included food bowl at all.

Here's the bowl I purchased:

I designed this to fit specifically into that elevated dog bowl and to be more shallow and "easier" for him to eat from, but it can be used without it. I tried a few different bowl depths and settled on the current value of 25mm - which still takes him about 3-5 minutes to eat.

I printed this specifically in PLA because from what I've read its more "food safe" than other filaments, but it definitely wont survive the dishwasher, so it's hand rinse only.

EDIT - I've uploaded a “blank” dog bowl STL for those of you who don't need the slow feeding portion.
