Sorry for bumping this topic, but it took so long for the puzzle to arrive.
The Master Square-1 is really a very interesting puzzle. Even if you only scramble it as a 2x2x2 only, it is already very confusing. And I don't dare to think, how much time I'll need for solving once I have really mixed it up. I was never very good at solving Square-1
I will have a lot of fun playing with this puzzle, because the mechanism is really very smooth. Maybe the small triangular pieces are a little bit loose, but that shouldn't be a problem.
I haven't checked, if the puzzle is available on Shapeways meanwhile, but if so, I can only recommend to order a copy!!
And because I think this information wasn't given in the original post
