eyeglasses mechanism 3d model

Design a compact retractable optical film mechanism for eyeglasses. Include a 2.0 mm diameter roller (48 mm long) with a torsion spring, holding a 40-micron thick tinted film (57 mm wide, 44 mm long). The film is attached to a 3 mm wide carrier strip and deploys vertically through side guide rails. The assembly is housed inside a subframe with a 3.2 mm internal height and 3.5 mm depth, fitting within a 6 mm thick top rim. Add a left-right slider that rotates the roller to deploy and retract the film. Provide full assembly, exploded view, and motion simulation.the mechaism should be inside the top frame side of the frame it should uncover and retract such that it covers the whole lens , basically the opticall film which is retracting and coming out covering the lens from the frony
