terraPin ACME 6X6 (6x9, 6X4.5) Pinhole Cameras - 120 film

The terraPin ACME pinhole camera is the culmination of years of 3D printing and camera design work. This camera is assembled WITHOUT ANY FASTENERS, using sliding joinery. With the exception of the pinhole (which is easy to make), all parts can be 3D printed.

NEW
A "Better Cap Plate" for the ACME has been uploaded. I have added a snap clip to the sliding parts that eliminates the need for an arched clip to hold the cap together. As before, you will need to remove the support under the rectangular insert, where the winders fit. Also "Snap Slider" caps have been added for the ACE and CAMEO.

The terraPin ACME uses medium format 120 film, which is widely available at photography supply shops and on the internet (Amazon, Lomography, eBay, etc). The format is a square 6X6 frame (12 per roll of film), and the photos produced have a classic wide-angle pinhole look with peripheral vignetting (darker corners, brighter center).

Pinhole Diameter: 0.22 mm
"Focal Length": 25.4 mm
F-Number: f/135

I archive all photos I shoot with this camera on Flickr.

Also included in the downloads is the ACE (f/135), a smaller 6X4.5 version that shoots a rectangular frame and makes 16 exposures per roll of film. A new 6X9 version, called the CAMEO, has also been included. The CAMEO will have extreme vignetting due to the short "focal length" and wide frame. Shoot the CAMEO at f/165, like the MUTO or terraPin 6*6. See MUTO for examples of this vignetting. Exposure calculations available in Thing Files.

See terraPin High-Strength Winder (1/4" shaft) for additional winder/knob options!
