A humble reusable water bottle design is presented, focusing on practicality rather than presuming to know users' needs. The innovative concept features a bottle with both ends open, which can be capped using various endpieces to customize the functionality according to individual preferences. Additional endpieces can be designed and manufactured by users or third parties to further evolve this universal platform for reusable bottles. The provided example endcap model includes a groove that accepts a standard O-ring for airtight sealing. This open-ended design not only facilitates easy and hygienic cleaning due to its open structure but also simplifies the manufacturing process compared to currently available bottles. A single bottle, when paired with different endpieces, can cater to all personal needs, offering versatility and flexibility. This unique design also opens up numerous business opportunities in various vertical markets by fostering endless customization possibilities.
