Bunk Bed

Bunk Bed

Bunk Bed is a 2x3x4 box with a hinged lid and 1x4 openings in the long sides. The goal is to put six pieces in the box. The flat pieces can get through the openings of the box quite easily. But the 3D pieces need a lot of space and use of the hinged part to get in. Once they're in, there's little room left for the flat pieces. In short, packing the bunk bed is a puzzle!

Printing Instructions

Print all parts as oriented in the STL files.

The frame, top and parts are recommended to be printed with 0.2mm layer height, 2 walls and 15% infill. You can add 3 walls and 50% infill to the pieces to give them a more solid feel. Seam alignment should be “aligned”.

Two sets of pieces are provided. One set highlights the individual cubes of that piece. Print only one of the two sets.

Improvements

For this puzzle you have the choice between the original files from Theo and Symen and an improved version by user "Crab". The improvements make for a better printing experience (the pin is hexagonal, some edges are rounded off). Also you get a set of pieces with groves, if this is what you like. But the puzzle is the same in all cases. And the pieces fir either way.

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.
