A magic folding „Fidget“ cube - also known as promotion or merchandising cube - built with Lego parts and fully functional.
About this creation
After some other 3D Lego Puzzles I had the idea to build a "magic folding cube". Cubes like this are often used for promotional or merchandising purposes. I have a picture cube from the first "Lord of the Rings" movie which works the same way. It's not really a puzzle when you play with it, but it was a puzzle to build ;-)).
The idea was to build it as small as possible with an edge length of two studs for the eight "sub cubes". The only possible hinges for such a cube were 1x4 / 2x2 hinge plates. I analysed the position of the hinges on my picture cube and tried to transform them into a working Lego model. I tried a lot of SNOT elements which all didn't work. Then Lego released a new inverted 1x2 / 2x2 SNOT bracket and the folding cube worked with it ;-)).
I wanted to put a black and white "checkered" pattern on the cube, just like I had done with my Soma Cube before. But the brackets only existed in black, grey and red, so I chose a black and red pattern instead. For that I seperated the hinge plates and recombined them.
This is the result:
A complete folding sequence: You can go on and on and on ...
The "snake" of cube segments:
So this is my magic Lego folding „Fidget“ cube.
I hope you like it :-))
