Yes, this was my octahedron cubie thingy.
I have now decided to put this as a giant puzzle. I don't know how bog the original mass-produced crystal cube is, but I'm pretty sure that is smaller than this. This puzzle is about 10.5 centimeters long (rough guess). As for the construction, I first took all the corner cubies out of a dollar store rubik's cube, then using six of those cubies, I put them on the center caps so that this is fully functional.
For this, I used paper stickers. For all the non-white stickers they were all from post it notes. The white stickers were basically from tags. (I am not allowed to use cubesmith because it is online and requires a credit card. (I am only twelve years old.)(Ironically, mom let me use a razor sharp painting tool for cutting the corner foots off.)
The turning quality is a little better than last time. Before, I used gum in my cube, but now I am using superglue. I didn't use that mich to keep the rithets of the add-on pieces in place (so as to prooving the full functionality of the puzzle) so I am surprised that the new layer can turn without it falling off after several turns.
So here it is:

I think to mass-produced ones are regular (1.9 x 1.9 x 1.9 cm).

Okay, thanks.


You don't even exist.

That's how surprising it is to have made a puzzle more than five times bigger than the origional!

he's talking about the size of the cubies I'm pretty sure.
if it was that small then yea it would be smarter than a pocket cube. so it's actually about 57mm, like a regular rubik's cube.

So it's a maxi rather than a giant?
