Double Drawer - Câu đố xếp hình thông minh

Double Drawer

The two facing drawers in the cage have the same volume as the four tetracubes/tripods that must be packed in them. An obvious conclusion could be: no problem. But both drawers have handles that hinder entering pieces. The resulting packing-puzzle takes about thirty moves to solve.

The drawers should be pulled straight up, no bending them to and fro! Rotations are encouraged in this puzzle.

Note: if you build the original model, you may find, with your printer, tolerances are such that unintended rotations can be permitted that greatly reduce the difficulty of the puzzle. (see picture for an illegal move)

Printing Instructions

Print all parts as oriented in the STL les. No supports are required. One part requires super glue (CA or Krazy Glue).

The recommended print settings are 0.2mm layer height, with 2 perimeters and 4 top/bottom walls and 15% infill. The tripod pieces can be printed with 3 walls and up to 50% infill to give them more weight.

Each drawer has a separate handle to print. You require 2 handles and 2 drawers. Glue the handles onto each drawer and secure with an elastic (as shown in the picture) to ensure a solid bond.

For the pieces, two flavours are provided. Pick one and print 4 of the tripod pieces.

Inserting the drawers into the cage can be a bit tricky. You can put one side of the drawer into its two channels and gently bend out the other wall to insert the other side. You could also use a small blade screwdriver (as shown in picture) to help flex out the long wall of the cage when inserting the “peg” closest to the end. Be careful; too much flexion will cause a crack in the wall.

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.
