This (system of) modular flatly folding structure is designed as an easily foldable modular structure by the traditional folding method: a flatly foldable diagram spanned over one [simply connected] sheet of paper is not so easy to be folded even if it is modified into the diagram as viewed in the preceding article, so that the sheet is divided into modules with linking sub-modules as above. Both of these are based on the [folding structure of] bird-base.

A modification of the flatly foldable pattern appeared in the preceding article #7 to be easier foldable with respect to traditional paper folding methods.

The composition is based on the twisted folding structure around an isosceles right triangle, too, but the composed structure is not critical: i.e., the twisted folding angle [around an isosceles right triangle] in this case is smaller than the Brocard angle of the isosceles right triangle.
[Note that each example appeared in the previous articles #3 to #7 is critical: it preserves Brocard angle of given triangle that is concerned with the basic foldable structure in its flatly foldable structure.]

One more (flatly) foldable pattern based on a twisted folding structure around an isosceles right triangle.
