This card storage box is designed for Sony FX3 users who need to carry CF Express Type A, SD cards, and microSD cards together. Since I couldn’t find any model that stores all three types in one compact case, I designed this version myself. The interior holds 9 cards of each type (27 cards total). The model consists of four parts: Bottom, Top, Card Storage, and Lock. Assembly requires six M3 x 30 screws for a secure and durable fit—perfect for carrying in a camera bag.

This project is my first-ever 3D model design. I’ve never had any prior experience in this field, so this is truly my very first attempt. If you spot any mistakes, have suggestions, or see areas for improvement, please feel free to share — I’d love to learn and make it better next time 🙏 For this project, I used Autodesk Fusion Personal to create the design. Your feedback means a lot and will help me improve my future projects. 💡
