Stellated Octahedron Pendant




About: Industrial Design student at Eindhoven University of Technology

These pendants are created with the same pieces as the cubes in my origami bracelet. With just one extra fold, you can make a stellated octahedron, I believed it was called an octahedron, I searched images of octahedron and this showed up, but apparently a lot of people make the same mistake. But, thanks to ynze, I now know that it's called a stellated octahedron. I hope you like it!

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: What Do You Need?

I think it looks best when you use three different colors. Since you'll need twelve pieces, I used three sheets that I divided in four pieces. 
So, you'll need:

Three different coloured papers
A piece of wire
A necklace (or just string, whatever you prefer/have)

Step 2: Making the Modules

How to make the modules can be found HERE.

After folding them, all you need to do is one extra fold, a diagonal fold from the bottom left corner to the top right corner.

You'll need to make twelve of these modules.

Step 3: The First Corner

Take three different coloured modules. Using three different colours for the model will make putting it together a lot easier to follow.

Putting the model together is easiest to follow by looking at the pictures.

Start with putting the corner of the dark green module in the pocket of the light green module. Take the white module and put it's corner in the inner pocket of the dark green module, the inner pocket had been marked on the second picture.
To finish the corner, take the corner of the light green module which, at the moment, is next to the white module, and put it in the corner of the white module.

Step 4: Three Ways

There are three options to know where to put which module. 

When there is one corner of a module in the pocket of an other module, there is still a pocket empty. You have used two colours, so in the pocket will go the corner of a module with the third colour.

You can also finish corners. As you can see in the third picture, with one extra module you finish a corner. Since you've already used two colours, take the third colour and create a corner just like explained in step 3.

The third option has nothing to do with colours, you just have to count. As you can see in the picture, I've marked the sides with numbers. There will always be four sides. So, when you see three closed sides and one open, you know you need to close this side.

Step 5: Continue

Using these three rules, you can always add a module somewhere. In this step I've included a few more pics of putting it together, all using one of the three rules.

Step 6: The Last Piece

When you have followed these rules, there will be a moment that you have just one module left. Go ahead, place it!

Step 7: Givin' It a Loop

Sure, you have made an octahedron, but we where going for the pendant, remember?
Take your pieces of wire and create some kind of clothes hanger- like shape. You can do it the way you prefer, or follow the pictures.

Step 8: Add the Loop

Take one of the corners out of a pocket. This will give you a space to add the loop. Close the hole by putting the corner back in the pocket.

Step 9: Add the Necklace

Open the loop and add the necklace, then close the loop again.

Step 10: Done!

That's it, your necklace is finished. I hope you liked it!

I'll be teaching math, starting in a couple of weeks. You just gave me an idea about some hands-on math classes :-D

Btw, an octahedron is a volume with 8 faces with the same shape (triangles). They look like two Egyptian pyramids glued together at the base. I think your shape consists of several octahedrons.

Yes, before posting it I searched google images for origami octahedron and the results also showed this model :)

It says "stellated" octahedron, meaning gesterrificeerd in keurig Dutch :-)

Anyone native in English, please explain to us poor dutch folks what "stellated" means?

The shape in the picture is most definitely not a Octahedron. But gesterrificeerd, yes it is.

This is so pretty. I want one! How large are the papers you used? Could I use post-its? Thank you!

They were 9,5x9,5 cm before dividing them in four, so that will be 4,75x4,75 cm. You could definitely use post-its, although I suggest folding one piece with regular paper first.
