Dia Scanner Nikon Camera III

Attachment to fit on my Nikon macro-lens (diameter 74 mm) for digitizing 24x36mm slides. The clamp holds one slide (in plastic window) at a time at the closest focal distance. Four screws can be used tokeep it from falling off the lens.
Slides are digitized to approx. 8Mb color pictures.

For best results, aim camera+attachment at some sunny white wall.
Or at a computer screen that displays an off-white color.
Printed slow, with 120% flow on Ultimaker.
