The stencil does not clamp into the plastic hinge like the image appears.  It has a plastic frame that goes into the hinge and there is a couple mm of a step such that the same hinge cannot also clamp the metal stencil.  They must have known it was a shit design because they sent a piece of metal foil tape to attach the stencil to the plastic frame.  And there are no stoppers so it is easy to bend the stencil pushing down too hard.  This 3D printed China Trash isn't worth $5.
