This film hinge is intended to keep the connected parts touching each other when closed. This can be achieved by calculating a circular arc of the needed length then create a strip with constant thickness and finally apply fillets where the strip meets the object halves. The last step somehow shortens the loop, but in the real world this is not a problem, because the arc will never be circular and so the fillets have an influence on the arc's curvature but not on its functionality.
