SLO is a 35mm camera created by 3D designer Amos Dudley, every part of which is 3D printed, including the lenses (although those took about 5 – 6 hours to be sanded down by hand). Designed with a modular lens and shutter system, the lenses can be swapped in/out and longer exposure photos achieved using the shutter buttons along the top. More images of SLO below! You can also check out Dudley’s blog here, where he documented the entire project.
