SD card holder insert for film canisters

thingiverse

Insert for 35mm film canisters that can hold up to six SD memory cards. If you shoot digital but still feel some nostalgia for the old film days, this is for you. Store your memory cards waterproof and with style. On the bottom, the insert has a socket for a 18mm spring (I used this one), so it will raise upon opening the canister. Works without the spring too, but will be less comfortable when taking out cards. Should work with all 35mm film canisters that have an inner diameter of 30-31mm and a inner load height of 44mm. These measures are quite standard, but there are some canisters which are smaller and won't take the insert.
