About this 3D model

This is an edited version of Exkeks's "SD card holder insert for film canisters" (https://www.thingiverse.com/thing:1550029) I edited this modle by putting a cilender around the orginal model and filling in the area for the spring. I also made a bar to hold down the SD cards. A rubber band is (most likely) needed to keep the bar in place. The Holder can hold a total of 4 SD cards.
