Abstract:
1. A thee-dimensional structure comprising: a sheet of material having a plurality of bending strap-defining structures formed therein, the strap-defining structures being positioned to define a plurality of bending lines, each bending line having adjacent strap-defining structures defining a bending strap having a longitudinal strap axis oriented and positioned to extend across the bend line, and the strap-defining structures being configured and positioned to produce bending of the sheet of material along the bend lines; a first portion having a monolithically-formed first fastening structure, at least one of the bending lines, and a substantially planar surface; and a second portion fastened to the first portion, the second portion having a monolithically-formed second fastening structure, at least one of the bending lines, and a substantially planar surface, the second planar surface being skewed relative to the first planar surface; wherein the first fastening structure is aligned with said second fastening structure, at least one of the first portion and said second portion includes an area of warpage caused by alignment of said first and second fastening structures.
