Turn Around

Turn Around

Turn Around's challenge is to pack six polycubes into a rectangular box. The lid has a dovetail and must be turned to close. To make this possible, the positioning of the pieces is limited. Of the more than 5K theoretical compositions, there is only one solution. Finding this particular structure is quite a challenging task that requires spatial imagination and mechanical insight.

Printing Instructions

Print the 2 box pieces and one of the piece sets. You are all ready for puzzling no post processing required.

There are two sets of pieces coming with this puzzle. The intended solution inside the box is identical for both sets and are similarly difficult. Unfortunately the alternative set has an unintended second solution that is simpler to find. Thus the alternative set is published here only for archival reasons.

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.

The "No Problem Puzzle Collection" contains many puzzles with complicated boxes that would be too hard to model using open-scad. Additionally the original design files for the boxes have been lost due to a hd-fault. That is why these puzzles only contain scad-files for the pieces.

About The Designers

From November 2020 to April 2023 Theo Geerinck and Symen Hovinga collaborated under the trading name of "No Problem Puzzles" to design and produce their puzzles. Many of their unique packing puzzles introduce fascinating features such as moving or sliding doors and elements. These features and the way they behave always add a playful new dimension to the more familiar exercise of packing shapes. Those puzzles could once be purchased through an online printing service. Alternatively, for those who owned a 3D printer the files could be obtained from Symen.

However, after the tragic loss of Symen, purchases through the ‘No Problem Shop’ was no longer possible. Therefore, Theo decided to publish the designs so that everybody can create 3d-printed copies to be enjoyed for personal use.
