A Teeny Tiny 3D Printed Macro Extension Tube
https://hackaday.com/2019/09/04/a-teeny-tiny-3d-printed-macro-extension-tube/
When you hear the term “extension tube”, you probably think of something fairly long, right? But when [Loudifier] needed an extension tube to do extreme close-ups with a wide-angle lens on a Canon EF-M camera, it needed to be small…really small. The final 3D printed extension provides an adjustable length …read more (https://hackaday.com/2019/09/04/a-teeny-tiny-3d-printed-macro-extension-tube/)
