Modular Origami Octahedron
Learn to fold a sonobe unit here.
Modular origami octahedron. The finished piece of modular origami below is a stellated octahedron made with 12 sonobe units. These origami instructions use half of a sheet of a4 paper to create a 3d origami octahedron. Modular origami is a technique that can be used to build some pretty interesting and impressive models of mathematical objects.
This modular octahedral unit is completed by assembling 12 sonobe units. Modular polyhedra gurkewitz and arnstein 96 a system of origami polyhedra models is defined as a collection of models that can be folded from different numbers of a given module or from modules that have related folding sequences. Rona gurkewitz definition of modular origami polyhedra systems definition in the book 3 d geometric origami.
The sonobe unit is very versatile and can be used to make all sorts of polyhedra such a hexahedron a stellated octahedron a stellated icosahedron and many other irregular polyhedra. Anyway lets get started. The 12 unit sonobe ball.
Basically you slide the point of one unit into the pocket of another unit. Beginners should use 3 colors of paper. The assembly is probably simpler if you only use one color but you can challenge yourself and assemble a unit using 3 colors.
Learn how to make modular origami stellated octahedron ball with 12 sonobe units. How to make a cube octahedron icosahedron from sonobe units. In modular origami you combine multiple units folded from single pieces of paper into more complicated forms.
This is a fairly simple yet painstaking piece of origami it consists of 6 units joined together to create an octahedron. 12 square pieces of paper in this inst. Half of a sheet of a4 29 7 x 10 5 cm.
Practically it s 12 sheets of square paper and about 1 hour of your time. Mathematically it s a cumulated octahedron. A regular octahedron is a platonic solid composed of eight equilateral triangles four of which meet in the middle.
How to make a modular origami cubic octahedron tutorial instructions designed by toshikazu kawasaki tutorial by mica my paper. 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. Take a look at the images to see how to assemble units.
This sonobe stellated octahedron is made with 12 sonobe units created by mitsonobu sonobe. Things have rather escalated from there.
