Today, I made a 3 x 3 x 3 puzzle cube. I broke the 27 cubes it into 5 different chunks, with each cube measuring 20mm x 20mm x 20mm. My goal was to take these 5 pieces and fit them together perfectly into a cube. Each piece weighs about 3 grams and will take about 20 minutes to print.

Settings:

Layer height: 0.2 mm

Infill density: 20%

Nozzle size: 0.4 mm

Printing temperature: 200 degrees celsius

Plate temperature: 60 degrees celsius

Generated support material: yes

For my first piece, I dragged a cube from the side bar onto my work space, then duplicated it and dragged the next piece up and aligned it with my first piece with my snap grid setting at 5.0mm.

Then I dragged the top cube over 20mm to the left so it was only connected to my first cube on one plane.

I then added a third cube to connect the two other cubes.

I duplicated that cube and raised it 20mm to sit on top of the third cube I added.

After that, I duplicated the previous vertical row of three cubes, except for the cube in the middle. Then I selected all six cubes and colored them purple to represent them as one piece.

Following that, I selected all the cubes again and clicked the merge tool in the upper right corner to make them all one piece.

Not pictured, I created 4 other pieces using the same method as the one described above. Below is a solution guide for the puzzle cube.

…and here’s the final product!
