It should look like this before inserting the last unit:įinished cube. You should have 3 faces of the cube and one corner.Ĭontinue forming the cube. Now fold the squares together to form right angles and connect the units. Insert one Sonobe unit into the pockets of another unit: This post/video shows the process of making a Sonobe unit in more detail. When making the octahedron, or icosahedron you need to make an additional diagonal fold across the square part of the unit. There should be two triangular pockets that you can use to insert other units into. Tuck it into the bottom flap:įold the corners in to form a square. Refold the top corner down along the previously formed crease. Fold the bottom flap up to meet the middle crease: Start by folding the top down to meet the crease in the middle:įold the bottom up to meet the crease in the middle:įold the bottom corner up to meet the upper crease: Now you are going to fold the paper in fourths. You should have a horizontal crease in the middle: If you are using colored origami paper, flip it so it is colored side down: This seems to be a good size for modular origami. This makes crease marks that I cut along to make 4 square sheets that are 4.25 inches on a side. I like using smaller paper so I usually fold in half vertically, and then horizontally. The square created above is 8.5 inches on a side. Take an ordinary piece of paper and fold it diagonally. If you need to make square paper, here is a fast way to do it. Paper (square origami paper is preferred as it folds much better)Īll of the instructions below assume square paper is being used.In the rest of this post we are going to learn how to make the Sonobe unit and each of these models. Below are a few models that are easy to make using this unit. The Sonobe unit is a simple example unit from modular origami that is both easy to fold and compatible for constructing a large variety of models. In modular origami, you combine multiple units folded from single pieces of paper into more complicated forms. Modular origami is a technique that can be used to build some pretty interesting and impressive models of mathematical objects.
