Hello everyone,
Standard Mixup Cube's middle slices (M,S and E) can be turned by 45 degrees. What if we can turn them also by 22,5 degrees? It should looks like this:

Has anyone made this puzzle before?

That's perfectly possible. This would actually be the Mixup Cube III though; the Mixup II would be with 30 degree cuts.

Ask Luke, but 20 minutes before you posted this I told him I was thinking of making a Fisher Mixup :mrgreen:

Good Luck!

Do the cuts have to be curved for this to work? Or is this just your style?

At first I thought you figured out a way to remove my extra pieces by using curved cuts. However after some thinking about the look of this puzzle as a sphere, it MUST have gaps or extra pieces. Which did you use?

No, I just made them that way.

It doesn't have additional pieces (M slice above). I used conical sections. As a result mixup pieces (those from M, S and E slices) fit to corners (or edges in that case), but not to each other. I think these spaces between them are gaps you've mentioned, am I right?

However, I thought that sharp edges of pieces would harm turning quality, so I made their shape closer to square.

So the corners actually hold everything in like on the regular Mixup Cube, as opposed to how it works on the typical 3x3, where the centers hold everything in. I recommend that you make the feet of the mixup pieces thicker, so that there isn't a chance they will ride up over each other. The toughest parts to keep in are the centers, as they are only held in by the tips of the triangular tabs on the corners. Good luck!

Krystian,

For your Mixup Cube II you are using conical cuts... correct? So what does the crosssection of one of your slidey pieces look like? Is it concave in on the sides from these conical cuts? Have you made them square? If concave I'm assuming the slidey pieces only touch on the corners and there is a gap between them along their edge. If they are square I assume things have to be fudged slightly to allow rotation.

I'm just trying to understand how others deal with this geometry as I'm trying to close the exposed gaps in my Thorny Cube.

Thanks,
Carl

It's close to square, even a little convex. I started making a design with concave ones and everything was like you described it (pieces touching only on corners). Now, pieces touch each other on middle of faces. There are still gaps between them, but I think that way whole puzzle will better rotate.
Without additional pieces and/or planar cuts gaps are unavoidable in case of that puzzle, I think.
