This is plastic card protective case. Helps keep your pass/credit card a little bit longer.
Update 1:
Added locking spheres. If you print PLA it should be good now.
Update 2:
Locking spheres moved a little bit to make locks more hard.
Update 3:
More hard locking. Fixed an issue with unsteady edge near hole. Now its built using polyhedrons (both top and bottom parts).
