Design Concept

This mini TF card storage case is designed to attach to your keychain via a key ring, ensuring convenient use and easy portability. Its vibrant colors and clean lines add a touch of style, making it not only a functional storage solution but also a personalized decorative accessory. The surface-decorated logo can be customized; three designs are available.

Applications

Primarily used for the secure storage and transport of TF cards, preventing loss or damage.

Printing Recommendations

It is recommended to print using PLA filament, as this material offers sufficient durability. For items intended to be carried on a keychain, we suggest increasing the infill density—ideally to 50% or higher.

Assembly Instructions

After printing, assemble the snap fastener with the main body of the storage case. The connecting shaft for the accessories is made from filament material: simply cut one end at an angle, and it will slide in easily. The base is pre-drilled with a 2 mm hole, which can accommodate a small loop for attaching to a keyring. You can use 1.5–2 mm stainless steel wire for this purpose, or directly thread a small hairpin-style metal clip through the hole in the base.
