Description

This is an interlocking cube puzzle. It wil take 19 steps to remove the first part out of the cube. If you give this cube disassembled to someone there is a significant chance they wont be able to solve it.

This cube is by far the most difficult from the 3 impossible cubes. The cube can be assembled and dissembled with only linear moves. Doing so is very difficult. If you print the cube a little loose you can rotate one of the parts making the cube a little easier, but it will still be very hard.

The cube has 6 parts. There will be one part which needs support material to print. The other 5 can be printed without any support. You will get the .stl files to print this cube yourself. you can choose between 3 kinds of tolerance to print your cube: 0.25 mm, 0.15 mm and 0.05 mm. The assemble cube is 5 by 5 by 5 cm if not scaled. I personally printed the cube with 0.4 mm nozzle, 3 bottom layers, 2 wall layers and 6 top layers without any infill. If I want to give it to a small child I print it with 3 wall layers.

A burr puzzle can be ranked in two ways: level and steps. The steps are the total amount of movements which is needed to disassemble all parts. For this cube it takes 34 linear steps to completely dissemble it. The Level of the puzzle is the total amount of steps which it takes to remove the first part. For this cubeĀ  it takes 19 linear steps before you can take out the first part. To take all parts apart it takes respectively 19, 8, 2, 3 and 2 steps.
