Fold the top-left corner down and the bottom-right corner up to create diagonal edges.
The final piece will tuck into the remaining open pockets to complete the 3D structure. How to Fold Origami Paper Cubes
Making a paper cube is a classic origami project that can be approached in two primary ways: using a of paper to create an inflatable "water bomb" cube or using six sheets for a sturdy "modular" cube . Both methods require square paper and sharp creases to ensure the final shape is crisp and holds together without tape or glue. Method 1: The Inflatable Water Bomb Cube How to Make a Paper Cube Using Origami
Fold a square in half and unfold. Fold the top and bottom edges to that center crease.
: On the top layer, fold the two bottom corners up to the top peak of the triangle. Flip the paper and repeat on the other side to form a diamond shape. Fold the top-left corner down and the bottom-right
: Locate the small hole at one end of the model. Blow into it steadily until the paper expands into a cube. Method 2: Modular Sonobe Cube
This version uses six identical units (Sonobe modules) that lock together. It is much sturdier than the single-sheet version and looks great when using different colors. Both methods require square paper and sharp creases
This single-sheet method is popular because it begins as a flat, folded shape and "magically" inflates into a 3D cube by blowing air into a small opening.
