Chain drivetrain Free 3D model

This 3D model was originally created with Sketchup 6 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 This is a bit of an experiment in creating a chianlink drive train. The gear linkage at the back is a bit random, I know, but I was inspired by the 3D modeling challenge of creating a hover bike so I had that in mind when I was doing this.
