>>4149177I bought the files for a design called the Kraken 6x12.
http://frozenphoton.com/kraken/The design includes a focusing helical you can buy off ebay so you're not stuck with infinity focus.
My only complaint with the camera is that light leaks happen easily.
The film winding design doesnt make the roll tight enough when you finish it so you need to open the back in very subdued light
