Expandable Origami Coin Purse

Square shape by Angel Ecija Blanco

By looking at the crease pattern, I realized that you can fold other shaped boxes as well. Hexagonal & Octagonal versions calculated by me.

 

This is the second model that I folded from Angel Ecija Blanco's designs. The first one is the Self-Closing Twist Box (origamitutorials.com/self-closing-origami-twist-box/). Both designs share a few elements and are interesting to fold. You can read more here: origamitutorials.com/expandable-origami-coin-purse/
