Sorry CA but I'm with AFM on this. A living hinge requires specific conditions that can only be achieved when specific melt and flow criteria are being met. 3D printing cannot do this. You might get several flexions off a printed item but not the ridiculously high number as you would off an injection moulded item. 3D printed living hinges are for functional testing only.
