This Hand-Cranked 3D-Printed Machine Punches Sprocket Holes Into Photo Paper So You Can Shoot It as 35mm
Film photography's cost problem has a workaround: shoot paper. Jon Schiereck's 3D-printed perforator uses two modified drill bits and a rubber advance roller to punch standard sprocket holes into strips of blank photographic paper, producing loadable 35mm stock. A matching printable slitter is in progress, and the plans are free.
