4x4x6 Cuboid Twisty Puzzle
by TomZ, published
The 4x4x6 cuboid was first built by Tony Fisher from a regular Rubik's 4x4x4 in 2004. Joshua Bell commissioned the design of an open source 4x4x6 design in 2011.
The design for this puzzle is really quite complex and the supplied STL files are probably only printable on high-end printers such as Shapeways' SLS printers. Nevertheless, I hope the SolidWorks file will still be useful to many for learning the art of puzzle design or making derived puzzles.
The parts provided in the STL files have a wall thickness of 0.7mm, so they can probably only be printed in Shapeways' WSF material or on some other high-end printers.
For your convenience, you can order a pack of all the parts required to build this puzzle at Shapeways: http://www.shapeways.com/model/291445/4x4x6_cuboid___open_source.html
To assemble the puzzle, you will need 6 M3 screws (4-40 machine screws might work as well) and some M3 springs (about 10mm long). Using some small washers is recommended, and applying some silicone lubricant will improve turning of the puzzle a lot.
Additionally, I can sell you an assembled copy of this puzzle. Contact me at [email protected] for this service.
To open the SolidWorks file, SolidWorks 2011 or higher is required. I have tried to keep everything nicely organized in folders so the structure of the file is as clear as possible.
A zip file containing all the STL files is supplied for easy downloading (it's right at the bottom of the list).
