Retractible Cord Or RubberBand Battery

pinshape

A clever pull-string mechanism driven by a reliable rubber band. The spool's long posts offer ample opportunity to attach a gear, transforming this simple device into a powerful clockwork contraption or intricate pull-string toy. If extra length is not required, the posts can be easily trimmed to size. This versatile mechanism also makes an excellent retractable key leash. When combined with a Bic lighter holster, it provides a convenient and secure way to carry a lighter. Alternatively, the rubber band can be inserted between the two shells after being pulled through the central spool. By attaching the wheel to the posts of the spool, the shell will rotate freely around the spool. A great use for this mechanism is in creating a pull car. The powered wheel provides a smooth and reliable way to propel the vehicle forward, making it an ideal choice for building a fun and interactive toy.
