Picture of K2 - complex modular origami sculpture - no glue
Hi there :)

For those of you unfamiliar with the art of Origami, these are probably the models on this webside with the highest skill/price ratio :) They cost you nothing except time and a few sheets of paper...

Aaaaand, this piece of art is completely biodegradable :)

Here's a little bit of complex paper art for you to have some fun with. The assembly is very similar to Thomas Hulls 5 Intersecting Tetrahedra (there's an instructable for it), I would recommend folding that first if you haven't yet.

The original diagrams are in the OrigamiUSA issue of 2002 ( I think).

This is a complex rendition of a Great Stellated Dodecahedron, with 60 pieces of paper folded into 20 triangles comprising 5 tetrahedra. 

Oh and if I win the Epilog laser cutter with this instructable, I will use it to laser a labyrinth into a medical textbook of mine and put a ball bearing inside the book that one can roll around like a maze... I've been wanting to do this for a while, but I haven't gotten the opportunity yet, so if you're feeling nice then vote for me :) I might even post an instructable about it if I get it done...

What you will need:
10 squares of paper
CDO (Kinda like OCD, except the letters are in alphabetical order. As they should be...)

Ok lets get started!

the measures are in cm or inches?

Thank you for putting this up here. I've always wanted to fold this but I could not for the life of me find the diagrams. I've also made Gasherbrum, and Makalu, and currently working on double Makalu. If you want to see the pictures they are on my flickr page:

Looks fantastic, well done!
The diagrams are in the origamiUSA magazine issue of 2002 (I think).. But ya I agree, they were freakishly difficult to get hold of!
Byriah Loper has done some nice adaptions of the 20 intersecting triangles theme.
Happy folding!

Note: This is not my original work, this was originally designed by Robert Lang.
However, diagrams are impossible to find on the internet, and I would like other people to have the opportunity to make this beautiful model as well. So enjoy :)

Robert Lang's work is always impressive.

I detect a hint of spitefullness? :) I never claimed to have designed the model, all I did was make the instructions available to the public... If you want the diagrams, they are in the Origami USA annual collection of 2002 (But you'll have to pay for them!)

No, indeed -- to praise the one is not to damn the other. These are some very nice instructions.

But if you're asking me, I do think it important to give credit to the creator of a model and to ask permission, when appropriate.

You are 100% right actually... i'm probably gonna get into trouble one of these days...

I don't get step number 4?
joettle (author)  Artastic232 years ago
You need to fold the whole bottom edge up. There needs to be a line between the 2 short edges, connecting the guideline folds you just made.
The photo on step 5 shows it nicely :)
joettle (author)  Artastic232 years ago
This is quite a difficult fold, try to do it accurately. I found the best was to fold it bit by bit along the bottom, keeping the distance from the top edge kind of equal all the way. See what works for you.
