To prevent my cats of waking me up at 5 in the morning, i've modified an existing automatic cat feeder to fit my needs with two cats. Because they only get a specific amount of dry food at the morning and the rest of the day wet food, the machine will only run one time every morning and the cats will empty the bowl directly.

It would be possible to use the weight cell and holder from the single cat feeder, but I thought a dishwasher proof bowl from IKEA (https://www.ikea.com/de/de/p/kalas-schuessel-bunt-20421293/) with a holder would be nicer.

All the things are printable on an Ender 3 sized printer, for this i've seperated the base plate in 3 parts, connected via a puzzle like nose.
