Peanut Puzzle

3D model description

The Peanut Puzzle was invented almost 50 years ago by Stewart Coffin (his design #67). It consists of six pieces, all different. These pieces can assembled into many different shapes. By adding the optional pair of end pieces even more shapes can be formed. Over the years, Stewart Coffin has been generous in allowing copies of his puzzles to be reproduced.

This is a nice puzzle for kids, because there is no fixed goal and it is fun to explore ways the pieces can fit together. Adults will also enjoy the challenge of finding all possible shapes using the six basic pieces.

For more information about this puzzle, including the possible shapes that can be formed, see:

3D printing settings

Support structures are needed by all pieces except for #1 and the (optional) End pieces. I like to print each piece in a different color, so I include each in a separate stl file (combined in a single zip file).

Unfortunately, the area where pieces connect needs the support, which can adversely affect the fit. Carefully clean these faces to remove all support structures. A good fit may require further cleaning or sanding in these areas. Using water soluble support structures would probably improve the fit, but most of us don't
