This is one of only a few puzzles to combine twistiness with assembliness (write those new words in your dictionary).
It consists of three separate parts that fit together in only one way and in only one order. Each part is a mini twisty puzzle based on a 2x2x2 mechanism. Because of extensions on each part, moves often get blocked so algorithms must be adapted or new ones created. It's a bit like a Cubie Chaos puzzle that comes apart.
As you can see from the photos and video I have made two sticker variations of this puzzle. One has six basic colours and the other is covered entirely in gold (the gold doesn't show well in the photos) stickers. Without referring to photos or video both puzzles are very hard to solve. The six colour one is slightly easier since the colours tells you where certain squares should end up. The gold one tells you whether a square should be on the outside or inside but little else. The hardest version you could make would have no stickers at all. You would solve it by shape alone with no clues to where squares should go. This would be far harder than the two I made though less attractive unless all surfaces (inside and out) had a single nice colour (coloured plastic). To really understand my puzzle please watch the video.
The puzzles are a little larger than I would have liked but to ensure good quality I used 5cm Eastsheen 2x2x2s as a base.
I have started an ebay auction for this puzzle. The winner can choose either the gold or six colour version and I will keep the other.

My first attempt at solving the puzzle.

BTW if anyone wonders why I use repetitive captions and phrases it's to aid future searching. I am sure we have all tried to find things from years back and struggled.

That's pretty fun! When solved, do the individual pieces need sliding moves to go into their correct places (as in other burr type assembly puzzles) or do they simply fit together (like the SOMA cube)?

I think my video is the best way to answer that.

Are there any scrambled positions of the three puzzles that can still fit together into a cuboid, or is the solution verified to be unique?

Depends on how far you stretch the critria.

In any case your puzzle drives the concept of combination way farer. Kudos.

I think you are correct. I will change my wording.

The unextended 2x2x2 cubies could be swapped around and have different orientations but otherwise I don't think so.

Great idea Tony. I wonder if it would be possible to design pieces which could go together in more than one way but not show the correct stickers on the outside? Or design a "higher order" puzzle based on mini 3x3x3s? Mmmm ...

Hi Tony - I just have to comment on this one - I love it! What a great idea, and great execution.
I agree with Oskar - you should enter this in the IPP Design Competition.
In fact if you haven't already, you should show this to the usual suspects for mass production possibility.
