摘要： A polygonal sheet and a 3D structure formed therefrom, the polygonal sheet having a shape of an annulus sector comprising a first row and a second row, each comprising at least three panels. The 3D structure is formed by folding the sheet along the articulation between the first row and the second row, giving rise to a ridge when in an erect configuration.
