At home lay slides and negatives made many years ago. Slides have the property of being in a single copy. I decided to make a digital copy of the slide and present it to people captured on the slides. Here they are surprised! the Olympus working camera was lying idle at home. After playing a little with the settings, I realized that you can make a scanner. Sketched a future model in SketchUp and printed out a PLA filament. Nozzle diameter 0.4mm, layer 0.3mm. I cleaned it a bit with sandpaper and glued the parts with cyanocrylate instant glue. in front I glued the flask from a simple LED lamp. We insert the slide, set the super macro mode, point the bulb in a lit place (daylight, lamp) and take pictures. And voila! A slide made many years ago is converted to digital!
the finished model has a size 110mmx80mm, PLA filament, Nozzle 0.4mm, layer 0.3mm.
