About this 3D model

This SD card holder will keep your cards safe and together. The cap screws on within 2 full rotations and sits very secure, cards have very minimal play when the cap is on. Cards are very easy to remove and put in. 2 Cap versions: The closed cap will be more protective against the elements. The open cap is for paranoid people like me, who need to see if all the cards are present at all times. (also, looks really nice) The side dimples around the middle are also present on the closed cap, unlike in the picture.
