Moving Tank Tread

well what do you know, if you connect it to a box, it makes a tank tread! p.s. I read some reviews of other moving chains, just want you to know, i did not steal this idea from anybody! I made my chain before I even looked it up on warehouse....besides, isn't 3d warehouse for sharing ideas anyway? #caterpillar #chain #moving #physics #sketchy #sketchy_physics #tank #tread #wheel
