We are all makers
What better way to make the ultimate pinhole camera than to print one? Todd Schlemmer designed his PINHE4D camera to shoot 35mm film, using Tinkercad to create the files and a Printrbot Plus to output.
A more recent version is the P5, a 4×5 pinhole camera that was modeled after the Harman Ilford Titan view camera. It was designed around a widely available 4×5 film holder and has two focal lengths: 90mm, with a 70-degree field of view, and 150mm with a 46-degree field of view.
