Make a Soma Cube Out of Sonobe Modules

A soma cube is a puzzle made out of seven different shapes and must be assembled to form a 3 x 3 x 3 cube. To make a soma cube out of sonobe modules, you will need 122 units. Yes, 122.

(Click here to learn how to make a sonobe module.) 

The Seven Pieces (they don’t have to have different colors):

Piece 1, or “V”: 14 sonobe modules

Piece 2, or “L”: 18 sonobe modules

Piece 3, or “T”: 18 sonobe modules


Piece 4, or “Z”: 18 sonobe modules

Piece 5, or “A”: 18 sonobe modules (Don’t ask me why it’s “A” / “B” / “P”)

Piece 6, or “B”: 18 sonobe modules

Piece 7, or “P”: 18 sonobe modules


Making the pieces:

The same rule applies as the 12-unit sonobe ball tutorial: tuck the flaps into the pockets. What I noticed, though, is I get better results if I don’t “pre-fold” the sonobe module like this:

Rather, fold only where it is needed.


Once you’re done with the seven shapes, you can now form them into a cube! There are more than 200 solutions so get crackin’!

      1. Yeah that’s what I mean! I think I’ll be able to do it now thank to that close up picture! Thanks!

      2. Hi, sorry for the late reply. Not entirely sure what you meant by “full” cube, but it is a cube… It’s not hollow.

    1. I don’t have it with me right now but the final product is about 5″ x 5″ x 5″. The paper used was 3″ x 3″. If you want to make a bigger cube, then use bigger paper. I highly recommend getting a stiffer paper though, but not stock card thick. Maybe around 120gsm?

  1. I have that exact paper from Daiso! This is a really cool model and I will definitely be making more than one!
