My team, 1522 had designs for custom mecanum wheels that Andrew Brown (A senior at Hanover High School) developed through Autodesk Inventor. They didn't work as well as we had hoped, for the material we first tried to use turned to dust as we shaped them, so the subsitute material had much too little friction, so we slid a bit too much.
Nevertheless, I think the wheels looked amazing, and hope to use something like it for post-season projects.
