My shutter is a piece of dark foam (looks like a cube) cut to fit snugly into the front of the camera, I carved a cavity at the rear of the foam so it does not get in contact with the pinhole. I originally used this camera with a 0.03mm diameter laser drilled pinhole a pinhole manufacturer sent me for free, but diffraction was too much to get images, besides, 0.03mm is optimum for just a 0.66mm focal length camera!!. I substituted that pinhole with one made by myself with a diameter of 0.005", that is why you see 2 different f/stops written on the foam. Current f/stop is f/90.
Here is the shutter:
