Markus Split is designed by Oskar van Deventer, 3 October 2020 and is a four-piece cube puzzle. The puzzle is a 2x2x2 cube, where diagonally opposite cubies are connected. The puzzle-design challenge was to find a design with this property. This is my solution to this design challenge. It is based on a design by Markus Goetz, where each of his pieces is again split into two identical pieces. So the puzzle has four identical pieces.
The set of four pieces took 11 hours to 3D print on a Dutchy 3D printer. 131 meter of 1.75-mm PLA wood filament was used to print it: birch, oak, mahogany and black wood. Twenty-four 3x3-mm cylindrical magnets keep the puzzle together. The puzzle weights 74 gram.
Oskar van Deventer has created many different puzzles including his brand of Oskar Puzzles which are mechanical puzzles and objects that can only exist thanks to 3D printing technology. Since 1978, he has been creating hundreds of mechanical puzzles, making him one of the world's most prolific designers. Several of his innovative designs are commercially available.
