15mm macro extension tube for Sony E-Mount cameras. The extension tube goes between the camera lens mount and your lens and makes your lenses as macro lenses. By moving the lens forward it will reduce the minimum focus distance to the point where you can use pretty much any lens as a macro lens.
 

This doesn't support autofocus, so you'll have to focus by moving your camera backwards or forwards until the subject is in focus. You'll also need to make sure your lens aperture at the max before you attach the lens to the adapter as you won't be able to change it.

Sample pictures are taken of an old AMD Phenom II with a Sony A6000 and the Sony 16-55mm kit lens, which has a minimum focus distance of about 25cm. With this adapter it is close to 5mm at its widest focal length.

This needs supports, and print it with 4 perimiters and about 15-20% infill. To avoid light leaking into the adapter print it in black, but I printed mine in white and I have had no issues
