Introduction: DIN A: Dipyramid-to-Parallelepiped (and Beyond)!

By
About: The DIN A Dipyramid Project: The paper is readily available, and becoming familiar with just one simple fold pattern leads to all manner of creativity and discovery. This is because the fundamental design uses…

Using our standard fold pattern, one knife cut, and two pieces of tape, we can bring a single sheet of DIN A paper to life!

Supplies

One sheet of DIN A paper, a straightedge and cutter, and two pieces of tape, are all that's needed. For a sturdier, more durable model, a heavy weight paper like the A5 used here which weighs in at 160 GSM, is recommended.

Step 1: Fold

The fold pattern requires a total of 12 creases. I like to start with three folds which divide the sheet in 4 equal parts along the long length of the sheet. Then I make the three folds that do the same along the short length. Next, I make the two diagonal folds, corner to corner. And last, I do the four diagonals, from center of side to center of adjacent side. See photos.

Step 2: Cut and Tape

To allow for our desired freedom of movement, a cut to the sheet must be made, and then tape is applied in such a way as to allow for the same degree of movement. See photos.

Step 3: Make It Move

Figures to be found include:

The Dipyramid, the Parallelepiped, as well as several transitional forms, let's call them hybrids of these two. See video.
