A fun little to print with flexible PLA. I like to think of it as a miniature robotic spine. This design flexes in one direction somewhat like a finger. I hope to design another with 3 string to facilitate 2 directions for something more like a neckPrints all at once the only assembly required is to add a length of stringYou can see it in action here: https://www.youtube.com/watch?v=uF-5lWgYl-A
