This small capsule can be used as an EDC accessory box, providing a convenient way to store and carry matches, pills, batteries, or other small items. The design includes a ring-shaped top, making it easy to hang on backpacks, bicycles, and other items.

The design allows it to be printed without the need for support, and it comes with optional "gaskets". If printed with TPU, it can make the capsule waterproof. In addition, the top adopts a "triple screw" design, allowing the lid to be easily opened and closed by simply rotating it in parts. According to the design, the box is about 3 centimeters wide and 9 centimeters high.
