Why redesigning the beach ball and how? 

The re-designed beach ball introduces self-floating abilities without the need for inflation. Conventional beach balls are typically made from non-biodegradable vinyl sheets, giving them a short lifespan and making repair nearly impossible once damaged. This project rethinks the water-related recreational ball as a sustainable, self-assembly design that is durable, easy to store, and environmentally conscious. trapped air The design consists of identical extruded diamond shapes that naturally trap air within them during the 3D printing process. Users receive three sets of connected airtight diamonds, which can be assembled into a complete ball by following the provided instructions.
