About this 3D model

I have two yellow labs, each is fed 2 cups of food a day: 1 cup in the morning, and 1 cup at 5:00 PM. After a few months of using a new scoop, I noticed they gained a bit of weight. The scoop happens to hold a bit more than 1 cup. I decided to make a new scoop that holds 7/8 cup when level, and about 1 cup when heaping, the normal way we scoop the food into the cup. This was designed with a fairly calibrated Cupcake CNC with a MK5 extruder in mind.
