Stackable measuring cup for rabbit food

I made this design for my daughter who has a rabbit. It allows to prepare the right amount of food for her rabbit in advance.Cups are stackable to take up less space and protect the food, it's for that there is a top for the last cup.Normally for these small pets you shouldn't feet more than advised. So every morning you give the good quantity quicklyI give also the STEP file to modify the pet name or to delete it.Black and Purple printed on Prusa I3 MK3S+ the blue has been printed on I3
