Here, in the Schlaboratory, our scientists are slaving over simple CAD programs, with the goal of designing the best-shootin', easiest-to-assemble 3D printed pinhole cameras possible.  With that in mind, the new terraPin ACME utilizes snap-together assembly, and bolt-free loading. In early trials, the slide-lock lid is light-tight and easy to use.  

At this time, the camera works best with the terraPin consumer winders (in nylon or metal), and off-the-shelf instrument knobs (1/4-inch shaft). Expect a revised winder-knob design suitable for FDM 3Dprinting soon. 

This last photo is a composite of two exposures, inside and outside, at the back of the moving train. The outside exposure was quick - a second or two, while the inside exposure took several minutes. I used GIMP software to stitch the two resulting photographs together. No other post-processing or exposure adjustments were made. 

All photos made with Fujifilm Velvia 50 slide film.  The optical vignetting is prominent in some of these shots due to the limited exposure latitude of this film. Black and white or color negative films may have less of this vignetting.
