## What can you make with sonobe units?

The system can build a wide range of three-dimensional geometric forms by docking these tabs into the pockets of adjacent units. Three interconnected Sonobe units will form an open-bottomed triangular pyramid with an equilateral triangle for the open bottom, and isosceles right triangles as the other three faces.

## How do you make an easy origami icosahedron?

Is modular origami hard?

Modular origami is an especially difficult form of origami. It involves making several pieces of origami that eventually fit together into one larger unit. Folders of all levels rely upon precise diagrams in order to create pieces that fit together flawlessly when making modular origami figures.

How big is a 12 unit modular origami ball?

I went home with a simple 12-unit Sonobe ball that afternoon and was very pleased with myself. Entry-level modular origami: the 12-unit Sonobe ball. Mathematically, it’s a cumulated octahedron; practically, it’s 12 sheets of square paper and about 1 hour of your time.

### What can you do with a Sonobe unit?

Last post, the Sonobe unit was introduced as a way to use multiple copies of a simply folded piece of paper to make geometric objects. In this post, we are going to explore that concept further by making two more geometric models.

### How big is a 90 unit Sonobe bipyramid?

Sonobe family: 90, 30, 12, 6 and 3 units. The 3-unit one is a trigonal bipyramid but barely counts! These have all been made with the slightly modified unit mentioned below. The 90 units one is the biggest Sonobe that’s really worth making IMHO: about 3 hours’ work

Which is the biggest Sonobe in the world?

The 90 units one is the biggest Sonobe that’s really worth making IMHO: about 3 hours’ work The 30-unit ball has the symmetries of an icosahedron (or dodecahedron ).
