@jnbankston,
I am not sure the Carloop team is planning on a case for Carloop.
I believe their idea was to keep it small and low-profile so that it would fit onto the OBD2 port of any car.
Also, it is desirable to not add anything which might reduce the signal strength of the WiFi, Cellular, GPS or other wireless connection.
Your best bet might be to 3D print something at a MakerSpace that will fit your particular vehicle.
