Hub for assembling a model of the "buckeyball" fullerene molecule and other interesting geometries. Sixty hubs and ninety dowels are required to create a full model. I cut my dowels out of bamboo skewers.

Floppy 2x3x3 is a tribute to Katsuhiko Okamoto's brilliant and award-winning Floppy Cube. Floppy 2x3x3 works like a normal 3x3x3 Rubik's Cube, but with one face completely removed.

A large version of the puzzle is available here.

The goal is to assemble the five identical pieces shown in the first picture into the ring-like structure shown in the others. Each of the five pieces is made from six dodecahedral cells, giving the puzzle its name. It is based on the 120-cell, one of the six regular polytopes in four-dimensional space. When assembled the puzzle is a part of the stereographic projection of the radial projection of the 120-cell to the three-sphere.

This is joint work with Saul Schleimer.

This is the Multidodecahedron. A puzzle that has all the parts from the Megaminx, Pyraminx Crystal, Starminx, Master Pentultimate and Pentultimate and requires you to solve them simultaneously. This puzzle was initially suggested by Carl Hoff, who coined the name Multidodecahedron.

Zig Zag Zog - You will learn to zig zag in three dimensions to solve this 5x5x5 maze, but watch out for the pitfalls! The dimensions of this maze are 24mm by 24mm by 24mm and the ball is 7mm in diameter.

Ethereal Maze Puzzles are mazes that you solve by rolling a ball through an innovative new three dimensional lattice structure which forms the maze paths. The goal is to roll the ball through the Labyrinth Maze from the entrance to the exit. An additional challenge is to navigate the ball from the exit back to the entrance.

Start by pushing the ball into the spring loaded entrance ( it looks like a backwards “J”). Tip the maze in different directions to roll the ball along the paths through the maze. Don’t worry, if you make a wrong turn, the ball will not fall out of the maze. If the ball runs into a dead-end you can just roll the ball back the opposite way and try another path, that’s all part of this fun brain game. When you reach the exit there is a spring loaded button to press to release the ball from the maze. The exit is in a corner of the 3D maze, where you will find a bar with the little button sticking out from the side of the maze.

Each maze game come with the ball attached by a little chain link cage for shipping. This needs to be cut off and cut open with scissors and the ball will fall out. Note that each larger size maze comes with a larger ball. The balls can quickly and easily be colored with a highlighter or marker. Let the ball dry for a minute after applying then roll between clean white paper to remove excess color so it does not rub off on the maze. Paint for plastic models can also be used. The orange, green and black balls in the pictures were colored with highlighters or markers. Coloring the ball makes it easier to track in the Labyrinth maze.

See for yourself how Ethereal Maze Puzzles take maze puzzles to a whole new level of challenge and fun. With their convoluted lattice structure they can also be enjoyed as captivating and intriguing sculptural works of art.

Gear Shift is based on an idea by Bram Cohen. This puzzle has eight gears around a cube. All gears can turn together. But it is also possible to pull the gears apart in two sets of four. Each set of four can be turned individually. And there are three ways to split the gears. The object of this puzzle is similar to Rubik's Cube: scramble it and then try to solve it.

Professor Pyraminx!

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.

What makes this unique is that it requires only four parts to build a 2x2x1 Rubik's style puzzle. No screws, pins, or caps necessary! Assembly requires a little ingenuity, but the Strong & Flexible material allows it to snap together. Don't try to disassemble it.

UPDATE: Version 3 corrects a cosmetic flaw that left visible gaps between the hollow pieces.

Thank you for checking out my CrazyPill Version 2. First I would like to give credit to Tom Z for designing the open source 4x4x6, and to Calvin Fan for allowing me to use the patented design as a shape mod.

This puzzle turns very smoothly. If you were to buy a CrazyPill from my ShapeWays shop, you will only receive the pieces. You will have to buy your own hardware which is 6 M3X16 screws, or for the Americans that is 4-40 screws, plus washers and springs however washers are not extremely important if you can't find any. Washers and springs can be used from existing mass produced 4x4x6 puzzles, as well as many other mass produced puzzles, however for screws, some M3 or 4-40 screws have a big head on them and will not fit. Some screws have a built in washer on the head and those are too big. Stickers can be ordered through Olivérs Shop HERE

Additionally, if you wanted a fully dyed, assembled and stickered copy I can do that for an additional cost. You can contact me at crazybadcuber@gmail.com for inquires to assembled puzzles.

Another option you can have, is to have each 8th of the puzzle dyed a different colour and give the puzzle the stickerless theme, however in my experience it's difficult to get all the pieces of one colour to be the same shade, as thicker parts of the pieces take to the dye differently to thinner parts of the puzzle. If you had done that and you didn't like the result, you can always just dye them ALL black again and have a black puzzle.
