More than a glorified rubber band, this round flexible rubber drive belt was intended for printer applications, but now is pressed into service to make robots. The circumference of the belt measures 17" unstretched. The belt can stretch by more than 50% (26-28" circumference).
Cross-section diameter of the belt is 1/8". Think of these as really big o-rings! Use with 1/8" pulleys, shafts, and other drive parts. The thickness of the belt also makes these suitable for use as a kind of tread for tank-style robots. Get several and experiment! New.
