Extendable, universal case for portable electronic devices

摘要

The present disclosure describes a case for portable electronic devices. According to various embodiments, a case may be capable of extending to accommodate different portable electronic devices. A discrete series of grooves within the case may provide the case with additional elasticity. A pattern of tessellations within the case may provide the case with additional elasticity. The increased elasticity may allow the case to be configured to frictionally engage and retain various portable electronic devices with slightly different physical dimensions.
