Description
Now this I'm particularly proud of. It was a spark of inspiration I had while holding a windowed icosahedron is one hand and a stellated icosahedron in the other. I used the same size paper to make each and as I looked at each, they were about the same size. So I thought, "I wonder if I could assemble the windowed icosahedron AROUND the stellated one?" As you can see, it not only worked but they PERFECTLY line up. Theoretically, you could do this with any larger shape, which I'll have to try in the future.And if you too want to make one, the stellated model is made using simple Sonobe units. More complex models would work as long as it stays the size. And the window units are the same as shown in the tutorial I made. This is the solid unit variation as opposed to the bow-tie in the tutorial. Again, as long as they are the same size, it would work despite it being a variation.

I apologize but I do not have one. In fact I had no idea what Patran is until I Googled it. It looks like a CAD program, is that right? So you're looking for a skeleton model or something close to it? Since this isn't digital, it's actually a paper model, I'll take a shot at describing it.
Both shapes are based of an icosahedron. The black model has it's faces pushed in then the inner most of the face is cut off. The silver model is a bit more simple, a stellated icosahedron. The combined shape I found out by accident. The halfway points on the stellated model roughly equaled the size of the windows on the open model so they are a perfect fit.
If you want some more solid numbers I have a tutorial for a variation on the black model: [link] The other model is formed using Sonobe modules (wiki page) [link] and finding a folding pattern for that is easy enough using Google. The starting size of the paper is arbitrary but to get the finished shape both models must be folded using the same starting size. This particular model I used 3" squares for both but I recommend at least 6" paper if you've never done origami before. You could make an entire model yourself since the folds are simple enough but you will have some headaches on the assembly. I've folded half a dozen of these and they still give me some trouble at times.
Anyhow, this wasn't what you asked for but hopefully it has some information you can use. Good luck figuring your own shapes out!

That's awesome! I love how perfectly the two models merged together

Thanks! Coincidentally I had not folded any origami for a while so I decided to fold another one of these last week. As repetitious as folding these 60 units may be it helps focus my mind or something close enough to that effect.

Awesome job, once again! Love the concept, and I agree with Tired-Al, the color scheme is great! How long did it take to make this??
👍: 0 ⏩: 1
Hmm, each model takes an hour or so, 30 units each, and then a little longer to assemble the two together. I normally take my time folding, listening to music, getting up to stretch my legs, etc. so I'd say if you needed one ASAP, I could have one ready in 3 hours.

Sounds a lot faster than something that I could pull off!

Dude!
This is really good.
And as for the comment you made above that there was luck, I'm not so sure. As I think that you've been doing enough of these things that there is an element of intuition that has been developing in your mind.

Someone, rather some dude, has been reading ALL the comments...
You are right about the intuition. One reason I like modular origami is it lends itself to complex 3D shapes. When I took some intelligence test, I scored highest in spacial reasoning. So raw talent honed by practical application helped develop my mind. I suppose I meant I was lucky in that I just happened to be holding each one in a hand at the same time. In a way, luck an art form in itself, or at least a part of my style.

LOL, if you're in school, you need all the sleep you can... sorry if this keeps you awake. 
Do you know how to make the window units? If so, you shouldn't have any trouble making one. I've got a tutorial for the bow-tie variation; same shape, different pattern. I'd be interested to see if there are other combinations possible too.
Good Luck!

Maybe it can be an example, it;s also Fuses work
Also I already got Fuses publication caled "Unit Origami Multidimensional Transformations" and few other books so no worry I'll figure it out, so you tell that those two different units are made from the same size of paper?
👍: 0 ⏩: 1
You're right. I had forgotten you folded one before; you've folded LOTS before.
If you have the book, you've got everything you need there. And yes, both models use the same size paper.

thanks for advices, at first I need to get out from those damn tessellations

It is a pretty good idea.
And the chosen papers suit the model.
Good work here

Thank you! You know, I've seen you around dA but I don't remember if we've commented on each other before. I really appreciate the comment since you have such incredible work and I'm sure you have a critical eye towards origami.

Wow, that was definitely inspired, it's awesome!
Now my mind is running wild with all the possibilities... I want to give it a try too

You already have a Sonobe ball, so half of it is done. And I've got the tutorial for the open frame unit in my gallery. You'll notice it looks different from what's above; I'll have to put another tutorial for this variation up since I like it a little bit more. I'd practice assembling the windowed icosahedron by itself first because when you build it around the stellated one it gets tricky.
But yes, it does open some interesting possibilities and I have no doubt you'll find it worth your while.

Cool, thanks so much for the advice

What a great idea! I can only imagine the excitement you felt upon finishing the whole thing and seeing how perfectly it fit.
👍: 0 ⏩: 1
Yes, I was quite excited but it is difficult to be giddy with energy and folding itty-bitty pieces of paper. There are 60 sheets total here, 30 silver, 30 black, and all of them are 1 1/2 inches or 3.5 cm depending on where you're from. I'm 6' 2" tall (1.85 m) and have pretty big hands. It takes LOTS of patience to work with such tiny folds and joints. The finished product ends up being about 3 inches in diameter, just enough to fit in the palm of my hand.
All that to say, to be excited and want to hurry but be patient and do things correct so you don't crush your work, that's one of the secrets of life right there...

Oh yes indeedy. I like folding small origami modules myself, so I am somewhat familiar with that sentiment. =O

If this is mind blowing, that explains why my brain slowly leaks out, thus making me more ignorant by the day.

Great concept, And it looks really awesome o-o I like the color choice.

I think I originally planned just black and white but thought foil would look better so I used the white equivalent. I had to use the flash since there are so many little crevices but in normal light it looks even more cool. What happens is the silver reflects the black depending on the angle you view it so it looks like the silver pyramids are shifting in size. There is only so much a photo can show.

yeah, but foil looks great.
I still have to take a picture of those foil tiny drakes I made.
aw.. But it looks amazing either way sir, no need to pick out the flaws that may not actually be flaws

Thus, I am very proud of it.
