This is one of the most well known variant of modular cube. And comparatively easier then other variant. I will recommend to start modular design with this one as it's lot more easier to assemble which is good to get inspiration to go through future difficulties. Here I use 14 X 14 square paper for the all 6 part of the cube. Infact any square paper will do. The segments are very easy to make as per Sonobe's design. Thanks for your time.

Paper to used: Any Square Paper.
