This is my printable version of the Voigtlander "Small Frame Device" seen in the manual for my Voigtlander Compur Rapid folding camera from the 1920s. This device allows the user to take photos that are half the width of the photos normally taken by the camera, allowing for double the number of exposures on a single roll of 120 film.

This was an accessory for Voigtlander 120 cameras (not exactly sure how many it would've worked with) but it's incredibly hard to find information about this thing online and even harder to get your hands on one.

This model isn't the exact dimensions of the model, as that one eneded up being too thin and wouldn't print well or block enough light for the mask to be effective, so this one is a little bit beefed-up. I currently have it installed in my camera along with a b&w roll of 120 film, and I'll update here when I get the results!

I have also included the sketchup file in case anyone wants to modify it, as well as the appropriate pages from my camera's manual. Enjoy!
