These 3D shapes have a lot of symmetry, though not as much as the Platonic solids. Questions about larger models will lead you to the Archimedean solids and the Johnson solids. Questions about coloring will lead you to the mathematics of graphs and networks (and big questions that remained unsolved for many centuries).
One seemingly innocent question can easily lead to a mathematical rabbit hole. Once you've mastered the basic structure of each 3D shape, you may find yourself (as others have done) pondering deeper mathematical questions.Ĭan you arrange the sonobe units so two units of the same color never touch, if you only have three colors?Īre larger symmetric shapes possible? (Answer: yes!)Īre there relationships between the different 3D shapes? (For example, the icosahedron is basically built of triangles, but can you spot the pentagons lurking within? Or the triangles in the dodecahedron?) Sonobe units, like these ones piled in a stack, can be put together to create 3D shapes. What you need to make this origami Icosahedron tutorial: - 30 square pieces of paper with size 9cm x 9cm.
30 UNIT MODULAR ORIGAMI HOW TO
How to make Modular Origami Icosahedron from 30 sonobe units. So, for a little effort you are rewarded with a vast number of models to explore. More by the author: About: Hello there, I am origami folder from Bulgaria :) More About origamite.
Many modular origami patterns, although they may use different units, have a similar method of combining units into a bigger creation. The building blocks, called units, are typically straightforward to fold the mathematical skill comes in assembling the larger structure and discovering the patterns within them. That's where you use several pieces of folded paper as "building blocks" to create a larger, often symmetrical structure. Each design comes with suggestions for paper size and pattern type to use, and most 30-unit constructions can be made from 12 units, as well. Any piece of origami will contain mathematical ideas and skills, and can take you on a fascinating, creative journey.Īs a geometer (mathematician who studies geometry), my favorite technique is modular origami. I'm a mathematician whose hobby is origami, and I love introducing people to mathematical ideas through crafts like paper folding. They were originally used for incense and potpourri which I guess is where the name comes from. The word kusudama literally means Medicine Ball when translated from Japanese.
30 UNIT MODULAR ORIGAMI FREE
There are various types of units, but regularity is often similar, so it's fun to imagine how they are made.Īnyway, 12 or 30 units are not so difficult to make, feel free to try them out.Both activities, however, share similar skills: precision, the ability to follow an algorithm, an intuition for shape, and a search for pattern and symmetry. Kusudamas are modular origami models where multiple units are fit together to form a ball-like shape. If you are interested, you can search for "Kusudama" or "くす玉" and find something better made. If you try to make the same thing, I recommend that you make one by one by bonding. It was so hard for me to make, because It will naturally collapse from the middle of making. I knew it was possible, but it was the first time I actually made it.

I think it's good to understand the nature of polyhedra. I will also demonstrate how to assemble a 30 unit model (stellated. I tried to find Platonic solid in “Kusudama” structure. This class serves as an introduction to Sonobe unit modular models - no prior modular. On the other hand Origami is usually square, so it is not impossible but difficult to make equilateral triangles and pentagons.The shape of “Kusudama” is a star-shaped polyhedron. The polyhedron known as Platonic solid is composed of equilateral triangles, squares, and pentagons. When 12, 30 or more units are used, the shape becomes more like a sphere, and in Japan it is called “Kusudama” and is used for decoration.
The units used in this project are square and can be combined alternately. It is better to use a paper medium density, otherwise Kusudama can get.

Make small pieces from Origami, and assemble them to complex structure. for its implementation you will need to fold the 30 modules.
