I have not been the most active blogger these days, mainly because I am experimenting with paper jewelry and well, that is pretty time-consuming. Though I enjoy making paper jewelry, there is nothing like folding a good solid modular origami to get one back in the blogging game! This modular icosahedron is a fairly easy model to complete and is folded from half a square. So 15 squares, cut into half gives the 30 rectangles required for the icosahedron. The base unit is Lewis Simon's Triangle Edge Module.

Some points to note:

* I worked with coloured copy paper (80 gsm), which resulted in a good, sturdy model.

* If you are working with single sided paper, be sure to start with the coloured paper facing down (as given in the diagram).

* If your model is going to be tossed around (and believe me, this icosahedron very quickly becomes a football!), then be sure to add a dab of glue at the joints.

The origami buckyball is the representation of the Buckminster Fullerene molecule - a stable form of carbon. The other 2 are, of course, diamond and graphite.

Some interesting facts about the buckyball:

• The buckyball family is an allotrope (different forms of an element - here, carbon) of carbon, very different from diamond and graphite.
• The buckyball is made from 60 atoms of carbon
• The shape resembles a football - 20 hexagons and 12 pentagons
• Each atom has 2 kinds of bonds - double bonds between 2 hexagons and single bonds between a hexagon and a pentagon

That is enough Chemistry I think!

As for the origami buckyballs, one version of these buckyballs can be made using PHiZZ Units. These buckyballs are very commonly done as they are made from squares and are relatively easier to complete. 

The other version of the buckyball, what I have done here, is folded from units created by Rona Gurkewitz and Bennett Arnstein. The units are folded from equilateral triangles. Cutting the triangles, 60 of them, is 50% of the  job! Folding those 60 triangles into the buckyball units completely another 30%. Assembling the units is what I found easiest and I believe that amounts to only 20% of the entire process :) And behold, a buckyball!

It is usually suggested that you use paper coloured on both sides. That ensures that the buckyball has the same colour throughout. But when I assembled with single-sided paper, I realised that the contrasting colours meant that I can clearly see those stars in the hexagon/pentagon faces. I like that. And maybe, one day, when I give it another go, I will try using copy paper and see how that compares to this one.

Here is the final cube from the book 'Modular Origami Polyhedra'. The Ninja Star Cube is also made from 12 modules. The one I tried is the second cube. This one is a bit more ornate than the original ninja star cube. It has got a couple more folds which gives a little variety to the folds.

Each face of the cube has the shape of the star in the middle. The star is clearer in the next picture.

Before trying the Ninja Star Modular Cube, I tried out one last cube. This is again from the book 'Modular Origami Polyhedra'. As before, this is from the chapter on Decoration Box System. Almost all the cubes have the same heading, namely, 'Modular Cube', so I am also using the same name :) To be more specific, this is the 8th cube in this chapter. The design is by Lewis Simon.

When I looked at this model, I liked the shape which is different from the usual cube shape. This looks a little like the last modular cube I did, but with more pronounced truncated corners. Assembling the model is different from usual for me. An interesting model to fold :)

Since making my last cube, I have made a few more cubes from 12 sheets of paper. All are from the book 'Modular Origami Polyhedra' . This one is a Sonobe Cube formed from Decoration Box modules. We start off folding as for the decoration box module and then add a few more folds to get the final module.

I first tried this model from 2-inch squares. Quite a tough job!! Folding these thin creases are quite painful, but not as painful as creasing paper that has already been folded 4-5 times!! My thumb took quite a beating! I would strongly advice a bone-folder for this model. Unfortunately, I don't have one, so had to make do with my poor thumb :(

As I had mentioned in my previous post, I tried out the modular cube variation, this one in orange. The assembly is the same as the modular cube. The only change, in fact, is the way the initial fold is done, so that the reverse of the paper becomes visible. So it is a good idea to use paper coloured on both sides, in contrasting colours. I preferred using single-sided orange coloured paper. I think it has turned out quite well :)

But in reality, folding the modules turned out to be an unexpected challenge! I had used the same paper size as in my previous cube (1.25 by 3.5 inches). Unfortunately, this model had a couple of additional folds, resulting in really thin strips. And folding those thin strips in such a small paper turned out to be painful!! I used a ruler to ensure that I got the folds right. Thankfully the paper was quite strong, I am sure I would have ended up tearing quite a few modules otherwise!

The decoration and modular boxes from the book 'Modular Origami Polyhedra' are beautiful and very tempting! The boxes are all cubes made from 12 modular units. They are quite easy to make as well. And I love the little windows in the cubes.

I had previously tried out the original decoration box and was quite pleased with the results. This time, I tried out the first of the modular cubes, which is actually a variation of Lewis Simon's decoration box.

This turns out to be much more economical than the decoration box too, since it is made from 12 rectangles in 1:2 ratio (a square cut in two). The decoration box, on the other hand, is made from squares. So you can make 2 of these modular cubes for each of the decoration boxes :) Naturally, the size of the cube is also smaller than the decoration box.

While folding the cubes, the one issue I faced was that, the backside of the paper (white in my case), can be seen peeking out in quite a few places! No matter how I folded it, the white was visible :( I guess paper coloured the same on both sides would have been better.

Well, I will be folding a few more of these cubes. The next variation of the decoration box is the next on my list, followed probably by the Ninja Star cube.
