Another oldy! I have done the diagram for the sonobe unit and a variation for a free magazine about Japan and japanese culture and that’s what this post is all about!
This unit is known as the sonobe unit since it is general belief that 薗部光伸 / SONOBE Mitsunobu is it’s author. Some doubts about authorship do exist however.
Various assemblies are possible; with this exact diagram (no creases added) the cube or hexahedron, then with some added or modified creases you can create assemblies with 3 units, 12 units, 30 units and even more (:
I like the sonobe variation diagrams for key chains. In the photo, my actual key chain; I did glue the units and sprayed the finished model with varnish and left to dry for 2 days… An easy to do key chain, unique in the world! (; have you ever done origami key chains? Oh, this one also has styrofoam inside for sturdiness!
Here is the diagram; it’s for viewing purposes since if it’ll be probably too cramped when printed. The original diagram for the magazine was different and I may or may not re-do this one for a printer friendly version. Probably not since I have a lot to do other than this and there’s so many origami related stuff I want to spend my time with. Sonobe is well known too, so… I’ll decide later.
On another note: I have been reading the comments! However it will take me a while to re-read and properly respond. I’m only one (;
