This Machine Makes 35mm (Almost) Film

A hobbyist named Jon Schiereck built a 3D printed machine that perforates photographic paper with sprocket holes, turning it into a strip that can be loaded and shot in a 35mm camera like film. The device uses ground drill bits as punches, driven up and down by a gear-and-crank mechanism powered by hand or a cordless drill, with a rubber roller feeding the paper. He's also developing a 3D printable slitter to cut the paper into correctly sized strips, and shares the designs for free via his Ko-Fi page.
