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.

DinoBram is yet another jumbling twisty puzzle concept by Bram Cohen. He calls this 24-turning-axes puzzle a "corner-turning rhombicuboctahedron". When turning, it changes shape and sometimes rotations are blocked.
Astroid Attack is a twisty puzzle like Rubik's Cube. It is based on Bram Cohen's "jumble" concept, where the geometry is no longer isometric and faces do not turn in regular steps of 360/N degrees. The size (volume) of this puzzle is the same as a 6x6x6 cm Rubik's Cube.
Size 8, 18.54 mm inner diameter. This puzzle ring is a design by Bram Cohen. Bram writes: "It has basically a a single trick, but that trick is so cute and understandable that I think it's a compelling puzzle."
Size 8, 18.54 mm inner diameter. This six-part puzzle ring is a design by Bram Cohen. Bram writes: "This six-banded design is a straightforward extension to the traditional four-banded design which somehow never occurred to anybody before me".
Big Boulder is a blatant case of twisty puzzle extremism. 1 core, 60 centers, 140 corners and a whopping 150 edges. That is a lot of pieces. And to make it more complex, this puzzle jumbles too, which means that some moves may be blocked by other pieces. This puzzle is based on the geometry of a Pentagonal hexecontahedron. You may want to look that up on Wikipedia. The object of the puzzle is to scramble it and then solve it to a state where each color only touches itself or black.
Half Turn Cube is a Rubik's Cube that only allows half turns. This makes it a different puzzle that is easier to solve. It was contrived by Takafumi Haseda, and first prototyped by Hidetoshi Takeji in 2007.
Split Hex is a twisty puzzle with forty squares and eight triangles. The puzzle has two hexagonal cross-sections and one four-fold symmetry. It is hard to describe all the possible twists of this puzzle.
Framed Cube is a hollow 4x4x4 Rubik's Cube with a visible 2x2x2 Rubik's Cube inside. So you do not only have to solve the outer surface, but the inner cube as well. Concept suggested by Per Kristen Fredlund.
Gerardo's Cube is a Rubik's Cube without edges. The suggestor and name giver of this puzzle is an active contributor to the Twisty Puzzles Forum. He uses this puzzle as his avatar. It used to be a conceptual puzzle. Now it is real.
Big Chop is a twisty puzzle like Rubik's Cube. It was named by Bram Cohen. The object of the puzzle is tor scramble the 120 pieces and try to turn them back. Twisty puzzle fans will be horrified to learn about the mechanism. There is a steel ball inside and all pieces have magnets that hold them around the ball. There is also a pedestal to support the puzzle. A special tool is needed to turn the puzzle.
PantaCube was inspired by the Cubedron puzzle, which was designed by Pantazis Houlis. As a tribute to Pantazis' work, I call the puzzle PantaCube. The puzzle has five square tiles that slide around a sphere. The object is to scramble the puzzle and then to get the colors aligned again.
Fractal Cube is a twisty puzzle, related to Rubik's Cube. When solved, it is completely flat. While scrambling and solving, it swivels in all directions. The puzzle has a fractal structure with a trunk, branches and leaves.
AntiCube was suggested by Jason Smith. It has the geometry of a square antiprism. Some fudging was needed to make everything fit. This twisty puzzle has ten turning faces: two square and eight triangular. It has only edges, that turn over and under each other in unexpected ways.
Oskar had his head 3D scanned. The eight pieces should be glued around a 2x2x2 Rubik's Cube with 24 mm edges (12 cm cubies). You may buy the inner cube from several sources, e.g. the Twisty Puzzles Shop.
Gift Pyramid is a pyramid-shaped twisty puzzle that can be taken apart when solved. It has a little spherical cavity that can contain a small object.
This puzzle was commissioned by Darryl Suskin, who used it for a wedding proposal to his girlfriend Michelle. On Thursday 5 August, Darryl gave Michelle the Gift Pyramid with the ring, she opened it, he proposed to her, she accepted and they lived happily ever after.
Geary Cube is a Rubik's Cube with gears inside. This way, opposite sides always turn in opposite direction.
As a result, the cube always displays nice symmetrical patterns. Although easier than the original Rubik's Cube, it will still take quite some thinking to solve this one. Transparent objet is the material of choice for this puzzle, so you can see the gears inside. The puzzle is an idea of Bram Cohen, worked out in 3D by Oskar van Deventer. See this YouTube clip. The prototype on the photos was made by George Miller, using a combination of white FDM and transparent object, the latter from Shapeways.
CAUTION, THIS IS NOT A COMPLETE PUZZLE. Frank Tiex and Carl Hoff suggested that I build plugs to enable shape-modding of Minimal Twist. These are the plugs that he suggested. Buy Minimal Twist itself here. Read more on the suggestion by Frank and Carl at the Twisty Puzzles Forum here.
Crazy Comet is a twisty puzzle related to Rubik's Cube. This one is based on a rhombododecahedron.
Additional info for twisty-puzzle experts: Crazy Comet is an umodded, unbandaged version of Okamoto's Bevel Cube and Adam Cowan's Helicopter Cube. It is the smallest isometric twisty puzzle that "jumbles". According to the definition by Bram Cohen, a "jumbling twisty puzzle" is a non-doctrinaire twisty puzzle that cannot be unbandaged into a doctrinaire one. Got it?
Unlucky Twist is a 1x2x13 twisty puzzle, related to the Rubik's Cube. It is a tribute to Ola Jansson, who found a telescopic mechanism to create extremely long twisty puzzles, including his own 1x2x5 design.
This is the sixth puzzle out of a series of six. It is a tribute to the Cooksey Maze by Richard Cooksey. See http://www.shapeways.com/model/113356/cooksey_maze.html --- This specific puzzle has a ring two different rectangular pins at an angle of 22.5 degrees, and a matching maze cylinder. It is very confusing to solve, as you have to check both pins simultaneously.
This is the first puzzle out of a series of six. It is a tribute to the Cooksey Maze by Richard Cooksey. See http://www.shapeways.com/model/113356/cooksey_maze.html --- This specific puzzle has a ring two identical square pins, and a matching maze cylinder. It is very confusing to solve, as you have to check both pins simultaneously.

See http://www.shapeways.com/model/113356/cooksey_maze.html --- This specific puzzle has a ring two identical square pins at an angle of 45 degrees, and a matching maze cylinder. It is very confusing to solve, as you have to check both pins simultaneously.
