The 4x5x6 Cuboid is the next step up from my 3x4x5. This puzzle was made at the request of Sigurd Wedel. Just like the 3x4x5 this one shapeshifts as 90 degree turns are possible on the 4x6 faces.
In the design I've used a mechanism slightly different from that of my 3x4x5 and slightly more like a V-Cube. The result is a puzzle that rotates very smoothly, even better than the 3x4x5. This puzzle is truly very complex, having more than 40 different mechanical parts.
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 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.

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.

Two open-ended Superstrings with the correct spin can be merged into a super-symmetrical cube.
The idea for this puzzle emerged when I was designing shapes based on two interlocked tetrahedra. Inspired by ideas from 'string theory' and 'super-symmetry', I began to search for shapes that were both symmetrical and as similar as possible.
Taking the two pieces apart is not too difficult; reassembling them back into a cube can be more challenging. Hold one of the pieces still; move the other piece through the correct sequence of lateral and rotational moves.
