Mecanum Ring

One of the first models I saw on GrabCAD was of Mecanum Wheel(http://grabcad.com/library/mecanum-wheel) by Scott Bruins which inspired me to create my own versions of the same (http://grabcad.com/library/mecanum-wheel--1) and (http://grabcad.com/library/another-mecanum-wheel) So this is a design of a ring inspired and dedicated to my initial interactions with Scott Bruins, who has genuinely helped me a lot in improving my CAD work. THANKS Scott.....................
