HP Scanjet 3570c hinge

This is the hinge of an HP Scanjet 3570c, it is a piece prone to breaking, either due to understress or degradation of the plastic from which it is made.

Update: I have created another model of the hinge, split in half and the rings that go over the axis a little thicker (HP Scanjet 3570c hinge v2), I did this in order to make it easier to place the hinge on the axes, since it is easy to break when trying to place it. This way, split in two parts it is easier to place. You can leave the two parts unglued, since the hole where the hinge arm is inserted keeps the two parts together, or you can choose to glue them together.
