Cubic Puzzle

Each piece is made up from a number of uniform squares creating unique shapes.

Sizes for the shapes consist of a minimum of 5 squares to a maximum of 15 squares.

The orientation and layout of the pieces ensure that they interlock together.

No clips or pegs are required to hold the pieces in places which means that the puzzle can be assembled and disassembled as many times as required.

The puzzle consists of 24 pieces that make up a 6 x 6 x 6 cube with only one solution, the purpose being to connect the interlocking pieces in the correct configuration to complete the cube.

It is difficult (but possible), to find the solution using only logic or trial and error.

All the pieces will be printed in on go and will be orientated in such a way that no supports will be required nor any overhangs be present.

Each piece has to interlock at a point or points either on the specific shape and its neighbours in such a way that the pieces can actually be assembled.

Once assembled each of these pieces and their neighbours will be held by surface friction due to shape tolerance and surface finish.

All of the individual elements are placed until the entire cube is completely formed.

The cube is not hollow and is fully formed of visible external elements and invisible internal elements.

Although, the vast majority of the elements are externally visible even if it is only by their ends.

Printing options:

First ensure the printer is correctly calibrated to print a uniform square otherwise asymmetry may result that may compromise the ability for a uniform fit.

Filament: PLA

Resolution 0.15 mm with 3 layer wall count

Infill Density:20% 

Infill Pattern: Tri Hex

Build Adhesion: Skirt.

No supports.

With these parameters:

25% of full size will take ~1h:1m, size 55.8mm x 40.8mm x 7.5mm

Print times are subject to hardware, software or other settings.

Post Processing:

Some post processing in the form of sanding may be required depending upon print quality and the filament used.

Update (22 Sept 2023):

Original version removed due to close proximity of two pieces & replaced with Version 2.
