Ball roller

thingiverse

This roller is designed for managing the 2014 FRC game's ball, boasting a 12-inch length and a curved surface that matches the ball's shape precisely. The 1/2" hex hole in its center enables mounting on a common hex shaft. Print the three parts of this roller - two part 1 and one part 2 - while still warm for easier installation. However, be aware that plastic tends to slip with the ball; using rubberized material as covering could enhance grip (spray-on, tape-on, or surgical tubing wrap).
