Puzzle Cube

To begin, I started drawing all the possible pieces that could be combined by 3,4,5,and 6 cubes to brainstorm.  Below is a picture of a few of them.

Then I played with the blocks and formed two puzzle designs.  I documented these two designs with multi-view sketching and isometric drawings (see below).

Since my first design is more complicated, with more interlocking pieces, I decided to continue with that design.  In addition it took two people more than twenty minutes each to do it versus the one minute it took to do the second one.

The next step was to make the piece designs on the computer, using inventor, see below.  The first image is the physical rough draft of the piece while the second image is the computer generated one. 

Below are the rest of my computer generated pieces. 

In order to see if my multi-view drawings and isometric drawings were easy to understand, I swapped drawings with a partner to have her assemble piece 2.  

She was able to build it, it can be seen below on the left.  On the right is the piece of hers that I built from her sketches.

I also made annotated drawings on inventor for each piece.   

Finally, I assembled the parts using inventor.  

After the assembly on inventor was complete, I used wood glue and wooden cubes to assemble my puzzle.  Below is the finished product.
