Sliding Doors

Sliding Doors

Sliding Doors is a Dynamic Space Packing puzzle, where the lid and two opposite sides are integrated into two up and down sliding doors. The goal is to completely put the three pieces in the box. It will be readily apparent that this necessitates frequent sliding of the doors.

Updates

2025/12/07 a new frame by user "Crab" is added. Here is what he said: "In this puzzle, because the top of the “door” is too thin, it is possible to twist a part free which is not in the intended solution. To fix this issue, I created a door with a much thicker top wall. I also had to modify the base to accept this door. While I modified the base, I also battered in the walls a bit to help with the friction fit of the doors."

Printing Instructions

Print two copies of the doors and one of the other files. After printing, slide doors into the grooves of the box and you are all ready for puzzling.

Attention: there are 2 versions of frame and doors. See updates above to see the differences between the original and the iproved version by "Crab"

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.
