For many years I have made my own pinole cameras. Recently I acquired a 3d printer specifically for printing cameras. One of the first was the terraPin 6X6 Incher in the 645 format which I found on Thingiverse. I used PLA and it was easy to print and assemble.
It is the first time I have used the 645 format, and I am finding that I am really like the aspect ratio.
