I'm new in this forum and to introduce myself I wanted to show you a MOC I made in january. When this design is replicated using another four bricks and attached as such, they interlock in a cube shape.
At this stage, the pieces can fit together modularly in cubic tessellations as large as you like them, and you can tile 'em up. I still have very few experience with this forum, so sorry if there already was a thread like this(which I do not expect). My question would be: Is it possible to build a perfect circle, that is split into 6 sections? It might help us to better understand your problem if you could explain it in more detail or with photos.
But be ware! this IS parts intense, 516 thick liftarms (5, 7 and 15L), 334 thin Liftarms (5 and 7L) and finally 516 long technic pins.
Also, the six parts must be stabil individually(and must not have to be connected to the other ones).
As you may expect, it has to turn inside of - or around - another circle(this second one does, of course, not have to be perfect). How can I build a LEGO Rubik's cube, I have 2 of them, and I've built them several times, but how can I build a LEGO Rubik's cube. While this looks like it would work, I can't imagine that it holds together through many rotations. If you are willing to build something a bit larger, there are some good examples available, but it looks like it gets fairly complicated.

You'll ahve to try with the 6x6x6 yourslelf, but the one stud is too small on the eastsheen 5x5x5.I'll try on the V-cube 7 when I get it.

Thank you everyone, I am thinking of making more and putting them on eBay, So do you think they would sell? You could put them on ebay but I don't think many people are willing to pay a lot for a couple of $5 legos glued using $2 super glue to a $10 rubik's cube. When I had my first fast DSL internet-connection installed (end 2001), I could finally start searching the web. I soon realized that it was not possible to build the middle and corner elements with the currently existing LEGO elements: to achieve smooth turning and prevent from blocking, the elements should move alongside each other following a smooth curve (circle). Once you've opened the original cube and removed the top layer, you can clearly see the circle divided in eight (not necessarily equal) segments.
Unfortunately I need studs on at least two sides of these cubes (to attach the coloured tiles to finish the cube), that's why I used this same basic principle throughout the design. I don't have any 4x4 round bricks; so I tried to combine 2x2 round bricks with 2x2 round corners.
The axes in the centre are not strong enough to hold everything together: gaps appear, big enough for corner- and middle- pieces to drop.
There is one thing I forgot to mention: the virtual creation of the Cube was my very first MLCad-drawing. It would seem to you, like many others, that the headlight piece is virtually useless to connect any bricks with a base bigger than 1x1. Makeing a 6-segment thing in Technic is no issue as there are plenty of parts that give you a 60 degree angle. You can either build a larger version than the traditional cube, or you can build something that doesn't stay together very well. One of the joys of puzzle building is the ability to be as creative as you like, there is no reason to use the standard color scheme if you like another one better. The one thing I didn't want to do was to throw all my LEGO pieces together (throwing them together is easy, putting the pieces back in their corresponding boxes will be much harder).
This was purely done for aesthetic reasons: the 1x8 tiles (72 in total) of one colour will all point in the same direction.
Now this does not divide very well by six but if you take 13L Liftarms instead of 15L Liftarms you will end up with 36 sections. I am sure that ths distances between the 2x2-plates don't allow a plate or block of arbitrary dimension to be placed between them.

Because I'm an AFOL (adult fan of LEGO), I simply entered the keyword LEGO in my search engine. The most important part is the centre: six axles in six different directions turning independant of each other.
It cannot be done with arches: if you're able to create a circle, it'll never be divisible in eight.
I carefully calculated the distance from the centre to the technic angle connectors (the circle). You don't always see where you need them in MLCad using view mode, just imagine were you need them (tip: use the "step by step" method from the partslist).
There should never be a point of contact between the wheels and the circle, but if there was one, the wheels will prevent from blocking. I wouldn't find anything interesting there, in fact I wanted to find other AFOL's showing their creations on a webpage. In fact, their webpages inspired me to create something special out of LEGO elements: Rubik's famous magic Cube.
Think the white axles away and you have eight almost equal pieces left.Next question is how to implement this circle into the cube. I've put this circle on a chequered page (studs size) to see what the minimum size of the cube would be. The best webpages I encountered in this early stage of web-searching were LEGO trucks and heavy equipment built by Dennis Bosman (some of his models would fit in the "Model Team" series), Original Technic Models by Jennifer Clark (the best of the best, considering my own interest in LEGO Technic), and Eric Harshbarger's LEGO pages (some of his models would really fit in one of the LEGOLAND parcs).
In a later stage (after I bought my own Robotics Invention System) I also discovered JP Brown's Cubesolver. I came up with a size of 8x8x8 studs for every piece of the cube (instead of 4x4x4 of the first version).
