3x3x3 Puzzle cube


The purpose of our assignment was to create a 3x3x3 Puzzle Cube that interlocks. We used Tinkercad for designing our puzzle cube. The basics of the puzzle cube consists of 27 cubes (3x3x3). Each cube measured 10cm^3. We had 5 pieces total with each piece consisting of 4-6 cubes. No one piece can be the same with 4 pieces extending in the X,Y, and Z direction.

Firstly change the SnapGrid to 5.0mm as it will make placing of the cubes easier. You will want to start with a basic box and place it on the SnapGird. The next step is to duplicate the cube with the duplicate function on the upper left hand corner. You will want to place it so it does not separate from the cube but is directly aligned next to it.

Next I started to create shapes that I thought would be best fitted to the puzzle cube. There is no one way to create the puzzle cube, but you will want to have an idea of how each piece will fit with one another. Once a piece is complete you will want to highlight all cubes and use the group button to make it into one piece.

I continued to assemble the puzzle cube, you will be able to easily make changes if one or two pieces do not fit as the puzzle cube is quite flexible

With the pieces being “grouped” you will want to change the color as to distinguish each piece and to have a better picture of how the puzzle cube will turn out.
