Functional Megaminx

Here is a Megaminx puzzle, a dodecahedron-shaped variant of the famous Rubik's Cube. The puzzle offers a more difficult challenge than the original 3x3 Rubik's Cube, and it provides an exciting and entretaining solving experience. 

The puzzle uses a ball core, and the centers are attached to it by 12 M3 screws, at least 12mm long. This ensures that no pops or damages to the turning mechanism will occur. So you can be 100% sure that nothing will fall apart when you solve it. 

To assemble the puzzle, you should start by screwing all centers except one into the core. Then slide the edges and corners between the centers until you arrive at the top layer. Then, you should place all the pieces of this last layer and then screw the last center into place. If you screw all 12 centers before assembling the rest of the puzzle, you won't be able to place the final pieces. Before placing the center caps into their places, adjust the centers' tightness with a screwdriver, until all the faces turn as desired. Then, the center caps should be press-fitted into place. If any of them is slightly loose, feel free to use some super glue. 

For a better experience, you can sand any rough surfaces in the pieces to make the puzzle turn more smoothly.

Enjoy!
