Cat feeder, Automatic feederbowl (passive)

I designed this automatic cat feeder, complete with reservoir extension.
It's a self filling bowl without the need for electronics or intervention...

It is however only suitable for cats that don't eat more than they need.

You do need a little bit of supports on the reservoir exit.

I printed this on my prusa mini, so any printer can print this size.

It took a lot of time to design and prototype this, so if you like it a donation would be very welcome.
