A 6 x 4.5 120 camera. The design was loosely adapted for 3D printing from a Voigtlander Besse. The camera body is intended as a platform for experimentation with different lenses. This item is in beta. Please note that this item has not yet been printed or assembled. Actual operation of the camera is entirely theoretical. Both the lens tube and the lens adapter will require modification for use with specific lenses. The camera does not provide a shutter, therefore, a shutter must be provided by manual shuttering or by using a lens and shutter assembly, such as a compur shutter.The camera top and camera bottom should attach to the camera body, either using ABS cement or by using small machine screws drilled and countersunk into the top and bottom. A drilling template may be provided.The film knob passes through the camera top and through the lock ring. Rotate the lockring into the lock position. Without a constant upward force on the knob, the lockring will not stay in place. Experiment with cardboard, neoprene or spring washers between the film knob and the body to provide resistance to keep the lock ring in place.
