About this 3D model
This is a 3D printable version of my sumobot design at http://sumobotkit.com. It was designed for Nodebots Day in Las Vegas, NV. We were looking for a low cost alternative to expensive robot kits. With a couple of servos and a microcontroller, this is easily under $50. If you need a version that can be easily made in bulk, try the laser cut version in the SVG file!
