Automated 3d Printed Pet Feeder

About the project

Everybody who has a pet know, how hard is to solve the feeding when we aren't at home. We also had this problem. We are going back to our hometown, on every weekend, but we can't bring our cat with us everytime. We leave there some food and drink for him, but he eat it on the first day. So here came that idea.

Story

Automated 3D Printed Pet Feeder

Everybody who has a pet, know, how hard is to solve the feeding when we are not at home. We also had this problem. We are going back to our hometown, on every weekend, but we can't bring our cat with us everytime. We leave there some food and drink for him, but he eat it on the first day. So here came that idea, I have to create something what can feed our cat, when we aren't at home. It works great and our cat don't afraid about it.
