2x2x2 made from a 3x3x3

[dChan]

On TwistyPuzzles.com I have read that it is possible to make a 2x2x2 from a 3x3x3- but how? I have an old 3x3x3 that I would like to change into something cool, so any ideas?

It's possible, but probably difficult/time consuming. You'd have to figure out something to do with the centers, and probably extend the corners in some way.

Possible mods for the 3x3 that are cool:

Pillow Cube
Round Cube (I'm working on this one right now; it will hopefully turn out to be completely round or near-round)
Half Truncated Cube
Keyboard Cube (easy to do if you have an old keyboard lying around)
Cylinder Cube

Keyboard cube? What is that?

Are there any puzzles that only require 1 3x3x3 to build that are of a different shape or size?

 

[choipster]

im also curious to know what a keyboard cube is

A keyboard cube is just a cube where keys of a keyboard are attached instead of tiles.

A 2x2 can be made from a 3x3, actualy a 2x2 is a 3x3 with overlapping corners. So, if you make the corners so big that they overlap the edges and the centers you have a 2x2..

Could you elaborate a little more, Erik? I am very interested in doijng this.

All of the ones I posted just need a 3x3, some sort of epoxy putty (for the most part, anyway), and tools to cut and sand. They all have different shapes (except the keyboard cube), too.

Just extending the corners doesn't work, since you cannot turn the cube (if you replace the edge cubies, then the replacements will get caught against the center pieces; if you don't, the part over the edge cubies will get caught on the cube underneath and also on the centers).

I wish there was a turoial for this! There is a tutorial for 2x2x3, etc. but not for a simple shape as a 2x2x2!

it's very easy, if you have an eastsheen 2x2 and take it apart you slam your had (cause of the easiness)

WHAT? I have no idea what that meant(I know its sarcasm but what?)

 

[AvGalen]

He meant: It is so easy, you could slam your HEAD. It is a direct translation from a Dutch saying probably ("dan kun je je wel voor je hoofd slaan") meaning its obvious/simple.

So he said: It's so easy that it will make you feel/look stupid.

 

[Erik]

only if you dismantle one that is...

 

[deKeijzer]

I think you have to sand down all the edge pieces so that they are more like shape (see attachment).
And use a spacer item about 1-2 mm thick, and attach the "stickers" (half the size of your cube) to the corners of the cube.

This is for making an overlapping cube?
