This holds 4 frame 35mm film negatives flat so they can be photographed with a camera. Can be customized for different film formats and different print materials.
Edit: I'm adding a six frame version. I found that some of the old black and white negatives I have were cut to 5 frame and 6 frame lengths. I had to make the spring thicker to to give it enough tension. I also used my IBeam library ( https://www.thingiverse.com/thing:2805833 ) so that I could remove some of the plastic. I changed where the spring attaches slightly and how I calculate the size of the spring. I found with six frames, the springs interfered with the alignment pins I use on my scanning setup.
I also have some black and white negatives that were never cut. I have not decided how I will deal with them yet.
