About this 3D model

With all the Micro SD cards in the camera bag, I was looking for a way to organize them, keep them from getting lost in the crevices and provide some way of determining which are empty, and which have been used. This is what I ended up with - a disc that stores 5 Micro SD cards, and you can keep track of the used ones by turning them over when you put them back in. The built in indexing will keep the disc from rotating accidentally, stopping with the opening over a card slot for card access, and in between for storage. UPDATE : While printing a few more of these for my various camera bags, I found the retention fingers were breaking off more often than I liked, so I changed the design a bit, and added slot identifiers on the front to better distinguish between cards.
