## Burrloop ### Interlocking Puzzle by Yavuz Demirhan Assemble a standard six-piece burr inside an unusual frame. Finding the perfect arrangement to fit the burr into the frame can be challenging, but with patience, the Level 7 solution will become clear. I'd rate this one as intermediate-difficulty. Thanks to Yu Chih Chang for providing the model for this design. ### Printing Instructions Print one copy each of `demirhan.burrloop.frame.stl` and `demirhan.burrloop.pieces.stl`, ideally in two contrasting colors. The frame uses "snap joints" so that it can be printed without supports. After printing, connect all the joints before attempting to solve the puzzle. Snap each male connector into a corresponding female connector (for example, the male connector labeled "A" should connect to the female connector with a matching "A" label on the interior). For easiest assembly, first assemble the frame components into two chains of three pieces each, then mate the two chains together. The joints are designed to be tight, and depending on the printer and filament used, you may need to tap them into place. If they come out too loose, a drop of superglue will make them more solid (in most cases this shouldn't be necessary, but unfortunately tolerances vary across printers and filaments). The snap joint concept is discussed further in this tutorial: Getting Started with Puzzle Printing. ### The Printable Puzzle Project The Printable Puzzle Project aims to make available high-quality open-source models of many puzzle designs. 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 library. The `.scad` file is included with this model in case you want to modify any of its 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.
