Wall-E Tracks system

This is a part of the Wall-E that I have been working on. It is the tracks system. I created it for the robotics program at Idaho State University. I teach in the program and the students needed a project to work on. I have currently printed all of the pieces on a Dimension sst1200es 3D priner. I then cast molds of the 3D pieces using silicon rubber. I have currently been trying different kinds of liquid plastics to see what is going to work best.
