The fly-spring:
A further spring now this one which pushes up the front cover of a hunter case is to make.
In a cutout of the case band this spring works where it is fixed by a screw.

Note: the inner bezel covers also here a spring nose which must be able to move in the range of the hinge and needs clearance.
A special detail with an acryl case is important.
A critical point is where the top of the spring nose can damage the soft acryl material when it pushes the cover up. This point gets an endstone to prevent damage.
