This uses a two motor system to provide power and speed to turn the hex shaft. The Tamiya twin-motor gearbox is a small (3-inch long) plastic gearbox. It contains two small brushed DC motors that drive separate 3mm hexagonal output shafts.
With this ball caster your project can pivot and move in almost any direction. There are two ball casters included, and height can be adjusted for various applications and projects.
