This is a one-print one-piece Pokéball. It does not hinge and the pieces are attached. The inside is hollow, so I would recommend only allowing supports on the outside to ensure the model isn't weighted to one side.
The bottom shell of the Pokéball only attached differently to the Pokéball to make it appear to be two shells. The same is true for the button (Visible on the cross-section thumbnail).
