slider double keychain

Key Protection and Carrying Mechanism

This design was developed to make the keys we carry with us every day more secure, ergonomic, and practical. The 3D-printed body fully encloses the key, preventing damage to pockets or bags.

Thanks to the sliding mechanism, the key can be easily extended when needed and safely retracted when not in use. The “Indoor” and “Outdoor” markings on the body help the user quickly recognize the correct orientation, while the directional arrow ensures intuitive use.

Key features of the design:

• Protective structure: Prevents scratches by covering the sharp edges of the key.
• Ergonomic use: The sliding system allows easy one-handed operation.
• Portability: Compact size makes it convenient to carry in a pocket or bag.
• Aesthetic and customizable: Available in different colors and sizes to match user preferences.

This product offers an innovative solution to the common problem of carrying keys, turning a simple daily object into a practical and user-friendly accessory.
