Origami Mette Unit Ring (HD)

A very nice, easy to make Origami Ring made of Mette Units. Folding one unit doesn't take a lot of time but making 18 of them can be a lot to do.
Difficulty: 2/10
Paper: 18 units made of squares (I use 8x8 cm squares)
Music: Kickstarter (pacdv.com/sounds/free-music.html)
