These are two of my favorite ones:
- Calendar "Pentagon" in a Tsuzura box (wicker clothes-box).
- Modular Cube with pyramids in a Tsuzura box (wicker clothes-box).
The Calendar "Pentagon" was originally designed by Tomoko Fuse, and designed as a calendar by Sara Giarrusso and Ramin Razani. You can find printable patterns, instructions, and more information about the calendar, in the Origami Deutschland diagrams page.
The Modular Cube with pyramids is a Sonobe cube, with inserts designed by Kunihiko Kasahara. The instructions can be found in the book Unit Origami: Multidimensional Transformations, by Tomoko Fuse.
The Tsuzura box is also a Tomoko Fuse's design. The instructions can be found in her book Origami Boxes.
I folded all the models with New Leaf Premium Banana Fiber Paper.
For the calendar I used the diagram called "Dodecahedron" large - 2013. Instead of printing one page per sheet, I printed four pages per sheet in landscape orientation, in letter size paper, so I got a smaller calendar (even smaller than the "Dodecahedron" small - 2013). I used 7" (175 mm) squares for its tsuzura box.
I used 4" (100 mm) squares for the modular cube with pyramids, and 8½" (213 mm) squares for its tsuzura box.
