Crusher

Crusher

The goal of Crusher is to put the four pieces in the box in the inner 3x3x3 area while keeping them intact. Both box and lid are latticework and to put the pieces in, use must be made of the space between the bars and outside the box. Manipulate the pieces with your fingers through the lattice, take care not to make unwanted rotations. (no rotations are necessary in the solution) Finding the unique solution takes fifty two moves, forty three for the last one in.

Printing Instructions

Print all parts as oriented in the STL files. The recommended print settings are 0.2mm layer height, with 2 walls and 15% infill. The pieces can be printed with 3 walls and up to 50% infill to give them more weight.

The square opening on the outer frame should be supported as shown in the picture. (organic support recommended) Other bridges across the tall, narrow openings should print fine without support.

Glue the two pieces of the inner cage together as shown in the picture.

You must push/force the inner cage down into the outer frame with some force (see picture). The cage can only enter the frame in the correct orientation. The cage is now captured and can move down and up one voxel in height.

There are two sets of pieces. Choose the look preferred and print only one set.

You are now ready to insert pieces into the cage and solve the puzzle

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.
