This is a Remix of @Physic_Dude Macro lens adapter https://www.thingiverse.com/thing:621794 ##### FEATURES The entire design has been dramatically streamlined into a sleek, fully cylindrical shape, significantly boosting resistance for heavier and longer lenses. It's compatible with the vast majority of Nikon DX and Full-frame type F mount cameras. Once one (or more) ring is securely locked onto the camera, you can easily set the aperture of your lens by rotating it on its axis - a game-changer for lenses that don't have manual aperture control. ##### TIPS Start small with 20mm. Not all lenses work well with larger adapters, but you'll still be amazed at the results. These adapters are perfect for use with other mount-type conversion adapters and old or fast lenses that offer full manual control. You can stack extenders to achieve even more impressive results.
