17×17x17 Rubik’s Cube-Type Puzzle
Dutch puzzle maker Oskar van Deventer designed this mindblender. It’s like a Rubik’s Cube, but has 17 cubes on an edge instead of 3:
When Oskar heard of the world records being set for twisty puzzles, like the 7×7×7, 9×9×9 and 11×11×11 by Panagiotis Verdes from Greece, he wanted to try his hand at setting a new record himself. With sponsorship from his close friend Claus Wenicker, Oskar set about designing and testing a number of prototypes, and his third attempt was printed successfully with Shapeways. Sorting and dyeing all 1539 pieces took Oskar 10 hours of work, followed by 5 hours of assembling. The result is an oversized (140 millimeter, 5.5 inches) and fully functioning “Over The Top” 17×17×17 puzzle.
It currently sells for just over $2,000.
