One of many things I like about being a subscriber of JOAS’ Tanteidan Magazine, is the little modulars that usually start each edition. Leafing through #191, I spotted a series of cubes designed by Jun Maekawa:

My pick of the cubes is his “Binding Cube”, a delicious little 6-piece modular whose layers lock so completely and tidily, the cube looks like it is one piece.

Folded from 3 squares of Tuttle duo each split into 2:1 rectangles. The module is relatively simply folded from thirds, the lock has layers of adjacent modules interleaving in such a clever way. Some of the modules were hard to place because the lock has very little clearance if folded accurately.

I like this model a lot, and am also happy with the colour choice.
