Pinhole Shutter for Hybrid-67
thingiverse
This is a pinhole shutter design perfect for use with 120 film cameras, whether paired with a bellows or a lens integrated directly into the camera body. The design's adaptability makes it suitable for cameras like the Goodman One, and I currently employ it in my Hybrid-67 design.
