It should be noted that the units above can be assembled into many forms including a 12-unit cube, a 30-unit stellated icosahedron, a 60-unit spiked pentakis dodecahedron, a 90-unit dodecahedral model, and even larger assemblies. Swan Sonobe: this unit is so named because the assembled models have a pattern which looks like the head and neck of an origami bird. modular origami ball, kusudama: Designer: Maria Sinayskaya: Created: February 2011: Paper ratio: 1:2 rectangles (squares or other type of rectangles are also possible) Units: 30: Assembled with: no glue: Diagram: Download PDF: Little Roses Kusudama variation from squares. Striped Sonobe: Obvious from its name, this origami unit forms striking stripes. If you're having trouble, use paper clips on the middle of the petals to hold the flower together until all the glue is dry. For best results, use a glue stick or liquid craft glue and let each connection dry before continuing. Snow-Capped Sonobe 1: When assembled, the white parts of the paper converge at the corner giving the appearance of snow at the peak of mountains. Glue the petals together to form your kusudama origami flower. When assembled, units form a white (back side of origami paper) pinwheel pattern, or a daisy pattern. Mukerji modified the original Sonobe Unit to generate pleasing variations.ĭaisy Sonobe. You can find folding instructions for this module on Ned Batchelder’s page. NOTE: Videos with a black frame and orange icon in a lower corner are available in the Origami. Click an image to view its associated blog post and video. The main conclusion of all this was that whoever came up with this design in the first place was very smart.Section 1: Sonobe VariationsMitsonobu Sonobe designed an easy-to-fold and versatile origami unit called the “Sonobe Unit”. Modular Origami Models of this type are also automatically listed in: multi-sheet More restrictive types: abstract modular, figurative modular, other abstract modular models, modular balls and polyhedra, modular box, modular cubes and cuboids, modular fractal, modular intersecting planes, other modular mathematical object, other modular polyhedron, modular spiky balls, modular stars, modular. Instructions for the model were published in Meenakshi Mukerji’s book, Marvelous Modular Origami, on page 18. On this page, you will find links to origami video instructions and blog posts related to modular and geometric origami figures including: Rings Garlands Boxes Stars Flowers. The crease pattern would look like this: However, that's only in theory! In practice, you can get away with folding the units out of squares, and even though they won't technically fit together perfectly, this effect will be completely swamped by the errors from your folding, the bending of the paper, the paper having a nonzero thickness, etc. Modular origami involves folding a number of identical units and then assembling them together in a single shape a flat origami star or a 3D kusudama. Once you’ve mastered the basic structure of a 3D shape, you may find yourself pondering deeper mathematical questions. So, for a little effort you are rewarded with a vast number of models to explore. This number is the correct width-to-height ratio you should use to get the units to fit together absolutely perfectly. Many modular origami patterns, although they may use different units, have a similar method of combining units into a bigger creation. Origami Kusudama Cherry Blossom Step 7: Make the 2 diagonal mountain folds. Origami Kusudama Cherry Blossom Step 6: Now fold A-X to A-C on the right side. You see, the reason these instructions work so well at all is thanks to the numerical accident that 0.5 + 0.25 tan 63 is almost exactly equal to 1, with only a 1% margin of error. Origami Kusudama Cherry Blossom Step 5: For the left side, fold A-Y to meet A-C. The best instrutions are available at WikiHow: Make a Sonobe Unit. Step 2: Build your first 'traditional Sonobe Unit'. The smaller pieces don’t need to be complex. That will help you understand instructions like these (Sonobe unit variations) comfortably. When many identically folded paper sheets are joined together in a larger model, it’s called modular origami. One far-from-obvious thing I learned along the way is that although the instructions above call for the units to be folded out of pieces of paper that are perfectly square, you should actually take them to be ever so slightly off-square. Step 1: Familiarize yourself with Origami symbols like mountain and valley folds. This led to quite a lot of distortion and warping, so I recommend sticking to normal paper. I tried making this out of some *extremely* stiff card.
