3D printed giveaway to send arround the world

Lately I've been working on flexibility in printing. One of the things that came out of this: https://www.printables.com/model/339814 An interactive postal card that allows the recipient to fold a 3D starfigure by pressing out the 2 basic figures.The cards are 100% flexible (3 layers 0.2mm = 0.6mm!) and will survive any kind of sorting machine. They can be folded almost in half, sending it as a regular postcard will not cause any problems.Merry Christmas and a happy Newyear! WimV
