Lens box, right and left

thingiverse

Strong travel lens case that fits perfectly inside a 45 x 29 x 17 mm Alcon Dailies contact lens container. When closed, an automatic lock forms between the two parts due to a carefully designed 6° angle between them. This clever design eliminates the need for any additional locking mechanism, ensuring your lenses are securely stored at all times. The friction generated by this slight angle is strong enough to keep the case shut tight on any type of surface.
