Start with a piece of origami paper, colored side

down. Make a valley fold along the centerline as

shown, then unfold.

Now fold the top edge to the centerline, and unfold.

Fold the right corner down to the crease line you

just made, as shown.

Then fold the top edge again to the centerline.

Make a mountain fold along the line shown, then unfold.

Re-fold just the top portion of the last fold,

as a valley fold instead of a mountain fold.

Now fold point A up to the edge,

pivoting around point B.

Make a crease

from point B down to point C.

Fold point D down as shown,

then make a valley fold

to form the bottom edge of the box.

Tuck point E under the flap as shown on the picture.

Make a valley fold along the line shown, then unfold.

Now make two (2) more pieces just like the first one.

Take any two pieces and place them together as shown.

First, the edge of piece 1 shown goes into the pocket

on piece 2 as shown.

Then the loose flap of piece 1 gets tucked into piece 2.

Now repeat these moves to connect piece 3 to 2.

Then repeat the step to join 3 to 1.

Tidy it up, and there is…

your completed origami triangular box.

Repeat those steps to make the lid and

complete your triangular box.

Let’s make your own triangular 3D box.
