Shamrock Box (simplified) variants
Here is a simplified version of my Shamrock Box. The original was based on a molecule which can easily be tessellated. However, with a single molecule used for a box, there is no need to connect multiple molecules and the model can be simplified.
The version to the right is the standard simplified one. As you can see, the pattern on the walls is different than in the original. The box to the left is a simplified and more paper-effective version: it is folded from a 12×12 grid rather than 16×16, making it possible to fold a much larger box (both are folded from same-sized paper). The cost is that the lock is on the outside rather than the inside, so that two side walls show yet another pattern.
