Modular origami boxes again. Each one is made of eight equal-sized squares (in most cases, 3-1/2") of paper: four for the bottom and four for the top. Most of the folding patterns were from books by Tomoko Fuse, with a few semi-exceptions described below.
The six boxes on the left side have their lids on. The biggest box (top left) was folded from 5" squares, the smallish one on the middle right was from 3" squares, and the smallest one on the bottom left was from 2-1/2" squares. Starting from paper squares with sides of length x, the measurements of the completed box are approximately sides x/2 and height x/4.
The "windowpane" pattern at the top left and bottom right originally happened by mistake when I couldn't remember Fuse's original version correctly; it's still pretty close in appearance, but the pieces lock together slightly differently.
The six boxes on the right side have their bottoms tucked underneath to show three sets of internal divider inserts, each one made from a separate same-sized square: diagonal halves (the orange one has a narrow trough that can be opened up to hold small additional items), diagonal quarters, and perpendicular quarters.
The latter two can be modified to merge two adjacent quarters into a single half; Fuse doesn't explicitly give directions for doing that, but it's a fairly minor variation. Some of these dividers can be further subdivided, as shown in a different pic.
(I should've remembered to include a "naked" box interior in this photo, but those are shown in some of my previous box photos anyway. I also forgot to include a perpendicular half-divider, but that may belong in a different set anyway since afaik Fuse doesn't provide instructions, though I'd be surprised if the pattern I came up with is truly original in terms of no one having ever figured it out before.)
