One way or another I find many commercial SD card holders either too bulky, expensive or not to my liking.
My solution makes use of an Altoids Smalls tin, and I enjoy Altoids peppermints, so I’m recycling something I’ve already purchased – green photography!
1 First obtain an empty and clean Altoids Smalls tin.
2 Measure and score a piece of thin card for the divider so that the central raised and folded portion is the same height as the inside of the tin with its lid closed.
4 Fold and trim the divider piece so that it fits snugly into the tin with the raised portion central and touching the inside of the closed lid. Carefully remove this piece and put to one side.
5 To stop the SD cards rattling about against the bare metal tin. Mark and cut another piece of thin card for the lid. Fit this piece to the lid.
6 Measure and trim a piece of thin card so that it fits snugly and lines the tin’s inside edge. Fit this piece so that it is a tight fit (the tin’s folded lip will keep it in place).
7 Finally, refit the put aside divider piece to the tin. This piece keeps the other pieces from falling out – if it is a tight fit you really don’t need glue.
The SD cards are a close fit, and with the thin card inserts on the top and sides, they make little noise and are not damaged when being carried.
I keep my formatted, empty cards on the left side and my full cards on the right. This way I know which cards are empty or full by sight.
The tin will hold six or seven SD cards in one side, ready to be transfered to the other side as you use them.
