So how would you like your very own rhombicosidodcahedron? I’m sure the answer is yes ( :) ) so I thought I’d make a tutorial on how to make your own masterpiece.

You’ll need some supplies for this project:
-card stock
-a straightedge (or, for you non-math people, a ruler)
-a craft knife
-glue (I like to use Elmer’s Glue-All)
-an embossing stylus (about $2.99 at the craft store – see picture below)

I made my own pattern for this project on my Geometer’s Sketchpad program. It’s important to use the rules of geometric construction when making your pattern so that all the shapes are regular. That is, the sides are all the same length. To save you the trouble, I am posting a picture of the patterns so you can print them out for yourself.

Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb04.jpg'

I recommend putting 6 squares to a page, 3 pentagons to a page, and 6 triangles to a page. Keep some space between each shape, though. You’ll need to print 5 pages of squares, 4 pages of pentagons, and 4 pages of triangles.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb05.jpg'

Now, it’s very important you keep these all the same size. Don’t make the pentagons bigger because you like bigger pentagons. If you enlarge one of the shapes, enlarge all the shapes by the same scale. It’s very important that all the sides of each shape are exactly the same length.

Just for fun, I thought I’d post how I constructed these shapes. This is what my screen looked like before I highlighted only what I needed and hid all the construction lines.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb01.jpg'

So now that you have your shapes all printed, it’s time to score! Scoring makes the paper easier to fold. You need your embossing tool and something to cushion your paper. I use a magazine, but a few sheets of paper work well, too.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb08.jpg'

I now plan on walking off 37 pounds, saying bye-bye to my jelly belly, *and* never feeling tired again.

If you are using light colors for your rhombicosidodecahedron, you will want to use light colored paper underneath when you are scoring because some of the ink from the magazine (or dark paper) will rub off onto your light paper.

An embossing stylus is like a metal ball-tipped pen without the ink. When you press down on your paper, it will leave an indentation so that it will be easier to fold the paper. Hold a ruler along the line you want to fold and trace the metal tip of the stylus along the entire length of the line. Press hard. You may want to practice on a scrap of paper beforehand. Or on one of the triangles since you’ll have triangles left over at the end of this project and if you mess one up, it won’t matter.

Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb10.jpg'

Of course, you'll actually be *holding* the straightedge while you are scoring. I just couldn't hold the camera, the stylus and the straightedge all at the same time. Oh yeah, and the picture isn't backwards. I really am left-handed.

This is what it looks like from behind.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb11.jpg'

I like to complete an entire page before moving on to the cutting. After scoring all the shapes on your page, grab your craft knife. I use a stack of paper underneath the paper I’m cutting so that I don’t cut the board (or table) I’m working on.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb12.jpg'

Cut your shape out, leaving tabs on each side. Here, I’ve cut out a square with its tabs. You can use scissors, but it’s much faster with a craft knife.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb13.jpg'

Once the shapes are cut out, it’s time to fold up the tabs. Because of the scoring, the folding takes no time and you get a perfect fold at the same time. Yay for embossing tools!

Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb16.jpg'

Once you have all your shapes cut out, it’s time to make friends with that bottle of glue.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb17.jpg'

Squirt some glue on a piece of scrap paper and push the cat out of the way because you just *know* he’ll start eating it when you aren’t looking.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb18.jpg'

Use your finger to spread glue on one of the pentagon’s tabs. Don’t use too much glue or it’ll take forever to dry. Be sure to cover the entire tab with a thin layer. I’ve outlined it in red.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb19.jpg'

Glue the pentagon to a square. Be sure the edges of the shapes match up correctly. I’ve highlighted the glued portion in yellow.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb20.jpg'

The front of each shape should be line up perfectly. Neatness counts!
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb21.jpg'

Glue a square to each side of the pentagon. It should look like a flower.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb22.jpg'
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb23.jpg'

Now on to the triangles! You need to glue a triangle to the side (not the end) of each square.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb24.jpg'

Once you let this dry, it’s time to glue the triangle to the neighboring square. This will form a shallow bowl shape. Make sure the tabs are on the inside of the bowl.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb25.jpg'
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb26.jpg'
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb27.jpg'

This is where your seams are glued.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb99.jpg'
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb98.jpg'

Now it’s time to start building up from this bowl.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb28.jpg'
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb29.jpg'

I like to glue the pieces on and then join them.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb30.jpg'
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb31.jpg'

Here’s where I decided to call it a night.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb32.jpg'
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb34.jpg'

You can stop here and use your half-finished rhombicosidodecahedron as a bowl. It’s really good for storing the rest of the pieces. But not for soup. Definitely not soup.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb33.jpg'

You’ll want to keep working until you have a square and two triangles left to glue down.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb35.jpg'

Glue down all but the very last triangle.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb37.jpg'

This is the only time you’ll ever glue two tabs at one time. Up until now, you should only glue one at a time. But for the last triangle, there’s really not much choice. Cover the triangle’s two tabs with glue and press it into place.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb39.jpg'

You might be left with a little ridge, but that’s life. It’ll also make a really great *back* to your rhombicosidodecahedron.
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb40.jpg'

Don’t try to press the triangle in too hard or you might crush your rhombicosidodecahedron and that would be tragic.

So that’s how you do it! Here’s your finished product!
Image hotlink - 'http://i20.photobucket.com/albums/b250/DrCoolJamz/Rhombicosidodecahedron/rhomb38.jpg'

I’ve decided to include some more information on rhombicosidodecahedrons. Here’s the Wikipedia entry on my favorite polyhedron en.wikipedia.org . . . and here’s a website with a link to a sound file for the pronounciation www.scienceu.com . . ..

I'm definitely going to *try* to make one. I got everything today (it took me half an hour to find an embossing tool that didn't use heat) and I just printed out all the shapes... my printer didn't handle cardstock too well, but I finally got everything. You did an amazing job, Megan, and I look forward to you teaching us how to make more polyhedrons... if you decide to :)

You're really going to make one? Awesome! You know, with the shapes I've posted you can make any of the five Platonic Solids en.wikipedia.org . . . and five of these Archimedean Solids en.wikipedia.org . . .

How cool!

I had no idea that's what they were called! How would you pronounce that? Did it take you long to make it?

kk~

Here's a link to the pronounciation. There's even a voice file you can click on: www.scienceu.com . . .
The first one I made took me about six hours. I didn't time the second one because I took the pictures and all, but it probably took me about the same.

Mathlover,

I think you're the coolest person in the whole world.

The end :)

I actually did it! It doesn't look as good as yours, but I'm just happy I did it :) I worked on it about 2 hours on Saturday and a few hours on Sunday.

I'm sure that would work great! The part you press the embosser onto will be on the inside of the polyhedron so you won't be able to see it anyway.

I also wanted to add that you can use construction paper if you don't have card stock. It just isn't as strong, but it still works.

That is so totally cool! I really like it. I will have to show this to my niece. She would love to do this although she may get frustrated if something doesn't come out quite right. I amy even try it!

You.

Are a genius.

I have a bunch of stupid and funny photos, and I was looking for a creative way to display them as a present for my boyfriend. I reckon one of those with photos on them would be uber great.

I'll post a photo when I do it :)

Well this looks more or less like a project that would make me want to kill myself...the outcome is really cool, just looks like so much work and I know I would lose patience and end up making it ugly = (
