This weave was first folded by Byriah Loper (I think.) Anyway the folding and assembly are surprisingly simple, but create a nice effect. There is obviously no glue involved. There are no official instructions/diagrams for this, as far as I am aware...
This model will take you about 10 hours to do in total, about 7 hours of folding and another 3 or so for construction. The beauty of modular origami is of course that you don't have to do it all in a single sitting, but you can take your time and fold a few pieces a day over the course of 2 weeks or so.
Kinda similar to my other instructable, K2, but substantially easier. This is folded using 20 equilateral triangles, which form 5 tetrahedra, which are then woven together in the classic manner.
The whole model forms a dodecahedron if you plot each of the vertexes in space. Great mathsy fun!
The model I folded was tiny, i would recommend using much bigger paper. I had to do a lot of it with tweezers.The diameter of the final model is going to be (roughly) 1,5x the length of each of your pieces.
What you will need:
60 1x5,5 rectangles (I used 1x6, but it was a little bit loose. I would recommend using something a bit smaller, but if you want to play it safe go for 1x6).
Some sticky tape (just for the construction, if you have super steady hands and lots of patience it's not necessary).
Tea and good music to keep you company (origami is not exactly a very social hobby!).
OK lets get started!
