terraPin ACE Pinhole Camera, Lulzbot Edition

thingiverse

The terraPin ACE, Lulzbot Edition pinhole camera is a culmination of years of my 3D printing and camera design expertise. I love my [Lulzbot](https://www.lulzbot.com/) Taz4, and the ACE prints beautifully on it. This compact design will even print on the smaller Lulzbot Mini. The ACE uses [120 film](https://en.wikipedia.org/wiki/120_film), shooting sixteen 6X4.5 exposures per roll of film. It is a little brother to the [terraPin ACME](https://www.thingiverse.com/thing:1724928) and snaps together without any fasteners, using sliding joinery. With the exception of the pinhole, all parts can be 3D printed. A standard tripod thread (1/4-20) is provided by a high-strength, replaceable printed insert or a metal flanged nut. 120 film, also known as "medium format" film, is widely available at photography supply shops and on the internet (Amazon, B&H, Lomography, eBay, etc). If you don't have a local photo lab, you can [mail your film away for processing](https://www.google.com/search?num=100&ei=cf8UWr2xHY64jAPi6o-4CA&q=120+film+processing+by+mail). The ACE is designed for a 0.23 mm pinhole, but 0.20 mm will work just as well, requiring a little more exposure time. I make my own pinholes [(and you can too!)](http://www.withoutlenses.com/articles/how-to/drill-your-own-precision-pinhole-apertures), but you can easily buy a laser-drilled pinhole from many vendors on the internet. Pinhole Diameter: 0.23 mm F-Number: f/135 Pinhole Diameter: 0.20 mm F-Number: f/165 Exposure charts for f/135 and f/165 are included for common film stocks in the "Thing Files" for download. I archive all photos I shoot with [the ACME family of pinhole cameras on Flickr](https://www.flickr.com/photos/theschlem/albums/72157671989013075). Hey Dual-Extruder Lulzbot Users! Included, at the bottom of the Thing Files, are two STLs intended to be 3D printed simultaneously with a dual-extruder printer: *Dual_Color_terraPin_ACE_Lulzbot_Body.stl Dual_Color_terraPin_ACE_Lulzbot_trim.stl* I suggest that the "body" STL be printed in an opaque black, and the "trim" STL be printed in Lulzbot Green. This is experimental, as I lack a dual-extruder printer to test it before releasing it to the public. You can learn more about pinhole photography basics in the mini-zine "Pinhole Photography Short & Sweet" (download PPSS.pdf, in the "Thing Files" section). Hey! Read This!
