## Knotty 6 ### Interlocking Puzzle by Yavuz Demirhan Assemble six identical pieces into the symmetric shape shown in the cover photo. _Knotty 6_ is a beautiful, elegant design that showcases six identical pieces with flat, simple shapes that interlock in a surprising way. This puzzle is not difficult to solve, and it's extremely easy to print, making it accessible to anyone who might be interested, regardless of their experience level with puzzles or 3D printing. A variant is included (see instructions below) where one piece is unlike the others, allowing for an alternate assembly as shown in the second photo. ### Printing Instructions To print the original version of _Knotty 6_, simply print six copies of `demirhan.knotty-6.piece.stl`. To achieve the color configuration shown, print two copies in each of three colors. To print the variant, substitute `demirhan.knotty-6.alternate-piece.stl` for one of the six copies: that is, print five copies of `demirhan.knotty-6.piece.stl` and one copy of `demirhan.knotty-6.alternate-piece.stl`. If you've already printed the original version, then you can print just the one extra piece and use it interchangeably with five of the originals. Finally, you may optionally substitute `demirhan.knotty-6.inscribed-piece.stl` for one of the pieces. The difference is purely aesthetic; `inscribed-piece` has the name of the puzzle and designer printed on it, as shown in the photos. ### The Printable Puzzle Project The [Printable Puzzle Project](https://www.puzzlehub.org/ppp) aims to make high-quality open-source models of many puzzle designs available. All of our models are posted with the generous permission of their designers and are licensed for non-commercial use only. Anyone may print copies for their own personal use, but selling or otherwise monetizing them is not permitted, and puzzle designers retain all rights as copyright holders of their work. Our puzzles are modeled using the open-source [puzzlecad](https://www.thingiverse.com/thing:3198014) library. The `.scad` file is included with this model in case you want to modify any design parameters; more information on how to do this can be found in the PPP Puzzle Modeling tutorial. ### About the Designer Yavuz Demirhan is one of the most prolific active designers of interlocking mechanical puzzles, with over five hundred published designs ranging from simple and bite-sized to highly complex.
