Very interesting! Much directed at the speedcubing community by the looks?

A new design for a higher-order cube? Now that's something that you don't see every day! Can't wait to see how it works, and good luck with that design in the future; you just might make some cash off of it.

The E-Cubes are my speedcube designs, which, of the ones I have produced, are the best that I know of. I keep changing my designs to try to make them the best. This is my fourth 7x7x7 design.

Very interesting. I would sharpen those fillets on the outside though. Might be hard to finger trick due to slipping.

I do not know when the prototype will arrive, but since it's late, this is my mechanism. 8-)

WOW!!! You just posted that statement yesterday. Were you expecting the prototype to be ready in less then 24 hours?

Either way I'm glad you changed your mind. This design is very interesting. I don't think I've ever seen a design for a higher order NxNxN where the corners weren't part of a base 3x3x3 that it was built up from.

Clearly you've been designing puzzles for a while. I find it hard to believe that you are new to the comunity. Is there an E-Cubes company out there that I'm just not familiar with? Have you been active on other forums before now? I'm just impressed by your design skills and I'm a bit taken back by how it appears you've just popped out of nowhere. Maybe I've just been too focused on these forums that I haven't noticed your work before and there are others here that have. Maybe I'm being too curious... but these designs are great so PLEASE keep up the work regardless.

Carl

Nice Job! Good to see another designer on the forum.


I do have a couple of quick questions on the design:

What is the function of the different radius fillets on the visible pieces? Some are quite sharp (inner + centers), while some are nearly quarter rounded (inner X centers). I can't tell based on just the pictures, but it is an interesting question...

Similarly, what is the function of the scallops on the corner pieces? Is it to allow smoother corner cutting?


I am really looking forward to seeing some of these designs in action!

The scalloping on the corners allow reverse corner cutting. They are present on Dayan 3x3x3s.

I believe Leslie Le's 12x12x12 used a similar style.

I have moved this from "New Puzzles" as that forum is reserved for completed works. Works in progress have a home in "Puzzle Building and Modding".

Ahh I see my error. I meant to say:

I don't think I've ever seen a design for a higher order NxNxN where the corners were NOT part of a base 3x3x3 that it was built up from.

Leslie Le's 12x12x12 is built up from a 3x3x3 but its the 3x3x3 corners which become the 12x12x12 corners. You can see that in his puctures. This is true of the V-Cubes and even Oskar's 17x17x17. What is new here is that those 3x3x3 corners are left as the 3x3x3 corners and there are now new 7x7x7 corners added to the puzzle which move OVER the 3x3x3 corners.

Looking at the design closer... I see those 3x3x3 corners no longer turn with the 3x3x3 layer next to the central slice layer. They appear to turn with the 5x5x5 layer just below the 7x7x7 face layer. Very interesting... You know... I think this means one could actually use this design to put a 5x5x5 inside a 7x7x7 and then use E-Cube's design for the 5x5x5 to put a 3x3x3 inside that. I guess I should be glad I finished my Real5x5x5 design when I did. E-Cube appears to be close to revealing his designs for what I would call a Real5x5x5 and a Real7x7x7.

I have been breaking it in for a while now, and it is way better than V-Cube or the cubic KO(I think that their cylindrical design is original, but most people call it a KO)

I have not had a single pop yet, and I solved it in 6:13, my PB for 7x7x7.
all inner layers cut corners at +22 and -5 to -8 degrees
outer layer at +35 and -10 degrees
outer to inner at +30 and -7 to -14 degrees
:D

I will post a video as soon as possible. :mrgreen:
