## ## No Holes Barred ### Packing puzzle by László Molnár Pack five pieces into a box with an unusual obstruction. _No Holes Barred_ is one of a series of challenging packing puzzles by László Molnár. It's perhaps the easiest of the series - four of the five pieces are identical - but that definitely doesn't mean "easy"! It's a very clever design and a solid challenge, with a tricky and surprising solution. Highly recommended to both novice and experienced puzzle solvers. Yu Chih Chang contributed models and photographs to this listing. ### Printing Instructions Print one copy each of `molnar.no-holes-barred.box.stl`, `molnar.no-holes-barred.pieces.stl`, and `molnar.no-holes-barred.obstruction.stl`. Ideally, print the box in one filament color, and print the pieces and obstruction in a different color. Before attempting to solve the puzzle, you will need to permanently attach the obstruction (the small triangular prism) to the box. The obstruction has three alignment pins attached to it, which are designed to fit into the three indentations on the inside of the box in one way only. Put a few drops of superglue (or other adhesive) on the surface of the obstruction, then glue it onto the inside of the box so that it forms a permanent connection. Once the glue sets, you're ready to enjoy the puzzle! ### The Printable Puzzle Project The [Printable Puzzle Project](https://www.puzzlehub.org/ppp) 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](https://www.thingiverse.com/thing:3198014) 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](https://www.puzzlehub.org/tutorials/puzzle-modeling). ### About the Designer László Molnár is well-known for designing puzzles that are based on a seemingly simple idea, but are actually fiendishly difficult. In recent years, Molnár's designs have featured prominently at the International Puzzle Party, and his packing puzzle _Hat Trick_ received a Top 10 award at the 2019 IPP in Kanazawa, Japan. A Google search for "laszlo molnar puzzles" will turn up lots of information about his designs, including links to several that are commercially available. Happy puzzling!
