thingiverse

Adapter to use 120 film in very old cameras that where made for 118 film, like the Kodak Autographic 3a and similar. The adapter has two parts, one that fits in the slot of the 120 spool and the cameras film winder, the other one is fits in the hole on the other side and is made to rotate freely in the camera. The fit is quite tight on some spools to make sure that the film will be held in the correct position. To use it: 1. Use a 120 film take up spool and load the film as usual. 2. Wind until you see the vertical arrow on top of your film roll. 3. Close the back and wind 8 full turns. The camera is ready to shoot! After each shot turn the winding knob 2,5 turns. Each photo will be aproximately 60x105 mm, if you want smaller photos just cut out some card board or 3d print a bezel for the size you want. IMPORTANT! Make sure that the red film number window is closed or taped over since it will not line up with the film backing paper and risk ruining your photos.
