Container Boot for Garbage Can

We use these Mainstays Clear Plastic Cereal Dispensers for garbage cans in our vehicles. We like them because they can be closed, you just put a basic grocery bag in them and it's easy to empty and keep garbage contained and smells inside the container. The only problem is that it keeps tipping over in our vehicles so I decide my first 3D design in onshape and came up with this concept (3D Design Here) Unsure if anyone else in the world will ever use this, but it is really helpful for me. I included the proof plate to print and test the dimensions.
