This Tiny Toy Could Be the World's Smallest Rubik's Cube

In 2016, a British puzzle maker named Tony Fisher set a Guinness World Record for building the world’s largest Rubik's Cube. The massive toy stood more than 5 feet tall, and was equally wide and long. To outdo this accomplishment, Fisher's next challenge was to create the world’s smallest 3D combo puzzle, according to Laughing Squid.

Judging from the videos below, Fisher appears to have pulled off the feat: His itty-bitty Rubik’s Cube is only a little more than half a centimeter wide, and it's smaller than the current record holder. That said, the puzzle maker probably isn’t going to submit it for World Record consideration, he explains on his website, as he filed down a larger Rubik’s Cube to make the toy and the final result wasn’t 100 percent proportional:

In June 2016 I took one of Callum’s 3D printed unstickered 6mm Subatomic Rubik’s Cubes and filed it down to a size of 5.4mm. Although I had made it smaller, the proportional aspect (cubies with square sides) of it was lost. So whether it’s still a Rubik’s Cube seems uncertain. When stickered it has an edge of 5.6mm. The previous smallest is 5.7mm unstickered or 5.9mm stickered by Evgeny. It’s proportional and there’s no question about its status as a Rubik’s Cube. The current official smallest is 10mm also by Evgeny which Guinness needs to update. I am not sure if I will submit this as a world record attempt. Not only is it disproportional but a huge amount of credit must go to Callum plus the 3D printing machine at shapeways that physically made the parts prior to me modifying them.
