This medieval-style box hides a small storage tray beneath a mechanical trapdoor lid. Turning the side wheel lifts the trapdoor, revealing the compartment inside while keeping the exterior looking like a solid wooden structure. The mechanism makes accessing the hidden tray feel interactive, turning a simple storage box into something much more engaging.

The design focuses on creating the feeling of a miniature medieval mechanism. The textured wooden structure and large side wheel suggest an old mechanical device, while the sliding trapdoor adds a sense of discovery. Opening it becomes part of the experience, making it ideal for storing small items, notes, or little valuables in a way that feels playful and secretive.

This design is also part of a personal challenge I’m doing for the year 2026: designing and releasing a brand new 3D printable model every single day for an entire year. Each design will explore a different idea—some practical, some playful, some reflective. If you enjoy following creative processes, testing new designs, or simply watching ideas turn into physical objects, feel free to follow along and join me on this 365-day journey.
