Mobius Kaleidocycle ... Material-saving design

This model is based on the paper "Single degree of freedom everting ring linkages with nonorientable topology"."Single degree of freedom everting ring linkages with nonorientable topology"という論文を読んで作ったメビウスカレイドサイクルですhttps://www.pnas.org/doi/10.1073/pnas.1809796115According to this paper, the classical kaleidocycle was reported by Bricard in 1927. This kaleidocycle consists of six basic units connected by six hinges to form a loop, and is characterized by the fact that it has six hinges but only one degree of freedom (i.e., it has only a fixed movement).この論文によると古典的なカレイドサイクルは1927年にBricardによって報告されているそうです。このカレイドサイクルは6個の基本ユニットを6個のヒンジで連結して輪にしたもので、ヒンジが6個もあるのに自由度が一つしかない（つまり決まった動きしかしない）点が特徴です。This paper reports a kaleidocycle that can maintain one degree of freedom even when the number of basic units is seven or more. The lower right object in figure 10 of the paper shows what the kaleidocycle looks like when the number of basic units is infinite. This is a "3π-twist Mobius ba
