Would it be allowed to create a 3D printed plate to go around it the official license plate. Ex: A license plate bracket that has the beaver from my profile picture on it. It would be non-functional, but just want to make sure.
Yes, this would be considered a non-functional decoration as described by <R7d>, provided that the official identification plate is still used underneath, and that the team numbers / alliance color are still clearly visible to inspectors and referees.
