An electronic device comprising: one or more electronic components ; and an enclosure that protects the one or more electronic components, the enclosure formed of a rigid material and including a flexible portion forming a hinge; wherein: the flexible portion comprises a first plurality of flex apertures defined within the rigid material along a first row and a second plurality of flex apertures defined within the rigid material along a second row; the flex apertures are formed so that sidewalls surrounding each aperture have different angular orientations throughout the thickness of the rigid material ; the second row is positioned below the first row; the first plurality of flex apertures are misaligned with the second plurality of flex apertures such that a first end of each of the first plurality of flex apertures is in a different vertical plane from a first end of each of the second plurality of flex apertures; the combination of the first row and the second row is repeated throughout a length of the flexible section ; and when a bending force is applied to the flexible portion, the plurality of flex apertures vary in shape and dimension, allowing the rigid material to bend. one or more electronic components ; and an enclosure that protects the one or more electronic components, the enclosure formed of a rigid material and including a flexible portion forming a hinge; wherein: the flexible portion comprises a first plurality of flex apertures defined within the rigid material along a first row and a second plurality of flex apertures defined within the rigid material along a second row; the flex apertures are formed so that sidewalls surrounding each aperture have different angular orientations throughout the thickness of the rigid material ; the second row is positioned below the first row; the first plurality of flex apertures are misaligned with the second plurality of flex apertures such that a first end of each of the first plurality of flex apertures is in a different vertical plane from a first end of each of the second plurality of flex apertures; the combination of the first row and the second row is repeated throughout a length of the flexible section ; and when a bending force is applied to the flexible portion, the plurality of flex apertures vary in shape and dimension, allowing the rigid material to bend. the flexible portion comprises a first plurality of flex apertures defined within the rigid material along a first row and a second plurality of flex apertures defined within the rigid material along a second row; the flex apertures are formed so that sidewalls surrounding each aperture have different angular orientations throughout the thickness of the rigid material ; the second row is positioned below the first row; the first plurality of flex apertures are misaligned with the second plurality of flex apertures such that a first end of each of the first plurality of flex apertures is in a different vertical plane from a first end of each of the second plurality of flex apertures; the combination of the first row and the second row is repeated throughout a length of the flexible section ; and when a bending force is applied to the flexible portion, the plurality of flex apertures vary in shape and dimension, allowing the rigid material to bend. <EOS>
