122 film spool

thingiverse

My oldest camera dates back to around 1912 and was designed specifically for use with 122 type roll film, which hasn't been manufactured since 1971. There are adapters available that allow you to utilize 120-sized roll film, which is still readily accessible, but this solution won't cover the entire picture area, as it's quite large. So what's the solution? You can either use individual sheets of film and load your camera in the dark before and after each shot, like I've done a few times, which works well for testing purposes but is somewhat inconvenient - or you can create your own 122 film by slicing and rolling it. However, to accomplish this task, you'll need at least two spools. My camera only had one spool, but fortunately, that allowed me to measure the correct dimensions for making more. Instructions: Print with an infill of at least 50%. Press the two halves together, securing them with a few drops of glue if desired. The ends of the spool are quite thin, so depending on your print material, it might be advisable to use black spray paint on the finished spool to make it more light-tight.
