Wooden Soma Cube (a 3D Puzzle)

Introduction: Wooden Soma Cube (a 3D Puzzle)

A soma cube is a 3D puzzle that your end goal is to make a cube. This is a great present for almost all ages, and you can build it yourself. Just follow the steps and learn how to build it yourself.

Step 1: Supplies

For this instructable you will need:

A thickish piece of wood (I used MDF)
Speed square
Something to cut your wood
Wood glue
Tape measure

Step 2: Cut the Wood

For the step, you will need to take your tape measure and measure the thickness of the wood. Then you will make marks that same size along the edge of the wood. Then you need to make marks along the other edge of the wood. The size of my marks were about 1 1 cm long. Take your speed square and make straight lines where your marks are. In total you should make about 27 squares.

Now cut along your lines with a hand saw, table saw, chop saw, or anything else you have to cut the wood in a straight line. You should end up with about 27 cubes. They should be a perfectly square.

Step 3: Assemble the Cubes

Now it is time to assemble the cubes to make your different shapes.

With your wood glue and clamps, you want to glue the cubes together to make the shapes in the pictures. Make sure you clamp them, because glue expands, and it will make your shapes uneven.

Step 4: Now That You Are Finished...

Now that you are finished, try to assemble the pieces together to make a 3 x 3 x 3 cube. This is where the puzzle lies. It is very hard to assemble the puzzle into a perfect cube, but it is also very rewarding when you do it.

    Very nice! We had this at home circa 1970 from Parker Brothers. Ours was light blue.
    I made this with a slightly different approach. I purchased wooden cubes from a local independent hobby shop*. They were already cubes. I glued them as described and painted them light blue. Now I'm trying to do the puzzles I found on the internet. They can be very tricky!

    *Dan's Crafts and Things, Rochester, N.Y. A package of 13 cubes cost $3.49. Michael's down the road had them for $5.49.
