Oskar Puzzles offers mechanical puzzles and objects that can only exist thanks to 3D printing technologies. All designed by M. Oskar van Deventer. 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, including Oskar's Cube, a metal maze cube that is completely hollow inside.
