Allows washing of photographic film sheets sized 4×5 inches and 9×12 centimeters. In theory, it also allows washing glass plates and paper of similar dimensions.

It is recommended to print using PETG or ABS plastics, although I printed the first version with PLA and, after more than two years, it is still working (even though it “sweats” through the walls).

Assembly instructions:

• In the bottom part (Part-A), insert a 1/2-inch bulkhead fitting.
• Glue together parts Part-A, Part-B, and Part-C using any hermetic method (I used dichloroethane).
• The fourth part (Part-D) is optional. It is a lid that prevents floating. When washing film, I have never needed it, as the film does not float. However, it might be useful if someone decides to wash paper.
