Fold Kamiya's geometric models without knowing wht they are

Postby Brimstone » July 28th, 2017, 2:52 am

This challenge is just for fun, anyone can participate.

At Kamiya's page about two thirds down of http://www.folders.jp/b/box/cp.html you can see 3 CP's that are clearly for geometric models. There are not (or at least I couldn't find them) pictures of the finished models.

Anyone want to fold them? If so please post pictures of the finished models. Printing paper with the CP on it is acceptable.

I'm pretty sure the first one is this: https://www.flickr.com/photos/magik9/9426077180

Are you sure you meant the first and not the third one? The first time I tried it I thought it was a cube with a pyramid on top.

I already did the second one and I'm preparing a good paper before I post a picture.

The third one seems to be some kind of lantern but I haven'tm figure out how to close it.

I have folded the second one:

I folded the second one, it's some kind of twisted pyramid, very ingenious.

I folded the first CP. It seems to be quite the same as the second one, only with a cube instead of a tetrahedron.

Kamiya Cube, folded by MotherOfThree.

Perhaps we could expand the challenge to all the CPs on that site? There are a lot of interesting ones, not only the geometric. As for me, I easily recognized the appearance of the geometric shape only by looking at the CP. That's somewhat more difficult with the other ones. Furthermore, it could be a more challenging task to only have the base of a complex animal, not knowing what it should be, than a polyhedron, whose final shape pretty much resembles its CP base. But that's only an idea.

That's what I got as well but the model didn't look like anything, so I thought I had done it wrong.

Go ahead if you want to. I wanted this to be a geometric model challenge since there are so many other challenges about figurative models.

MotherOfThree do you know that if you keep on twisting you get a cube?

Apart from the fact that my model is folded quite unneatly, it's clear though, that the twisted area in the middle of the CP should make two connected hexagons on whose the cube is "cut" apart. To the cube at itself, it's a bit tricky to lock it correctly, most of the upper (and lower) area of the CP is hidden inside the model. But yes, I'm totally sure that you get a cube that is divided hexagonally at the centers of its edges.

I didn't know that, that's why the model as I'd folded made no sense but today I took mine to our origami meeting and a friend who knew the model showed me.

Mine folded over the printed cp stays closed as a cube.

C'mon people, anyone willing to fold the third CP? I've tried but haven't been able to do it and I'm almost sure it isn't the model noneuclidean sugested it was.

I am also kinda sure, that it isnt the sliced cube.
I folded it myself, was able to somehow collapse it and was left with a cube and a strange triangle-like thing on the top and no clue what i had just folded.

That's exactly as far as I've been able to go.

If it's this one: http://www.folders.jp/g/2001/0101_c.jpg

I tried it and I got a cube with a tetrahedron on top of it.
The tetrahedron connects with the cube on the top diagonal. (the tetrahedron can be rotated on the diagonal)

Only solution I got at the moment. Not sure if it can be folded any different.
