The P6*6, a 3D printed Pinhole Camera.
The P6*6 uses 120 film and makes a negative 56 x 56mm in size. The source files are freely downloadable at http://www.thingiverse.com/thing:157844
I recently took my camera to Europe for Worldwide Pinhole Photography day, where I met a group of pinhole photographers in Amsterdam. I also went to London (and the science museum) and Iceland. All the pinhole photographs I have made with this camera can be seen here: http://www.thingiverse.com/thing:157844
I have designed other cameras and photographic accessories, all available on Thingiverse.
Hope you like!
