Summary

A simple camera obscura you can make with extra Google Cardboard lenses you may have lying around. The images of the obscura's images don't do it justice, it really is wondrous to see the mirror image world through this little box.

What You Will Need

            In addition to the 3D printed parts you will also need:

2 inch square glass mirror (can be found at craft/hobby shops)
2 inch clear plastic square (acrylic, polycarbonate, polystyrene, etc) ~0.8mm thick
25mm diameter, 45mm focal length Google Cardboard VR lens
400 grit sandpaper (or other fine grain sandpaper)

Parts before assembly

Putting It All Together

The lens may be pushed into place. Its not the tightest fit so I recommend gluing it in place. To assemble the mirror first slide the 3D printed spacer then the mirror and you are done. Likewise you may also glue these components in place once you are ready.

In order to get an image on the viewport you will need to sand the clear plastic square. When it is sanded enough you will not be able to see the lens or mirror through it when inserted into the camera obscura's viewport slot on the top. Below is an image of a viewport that is nearly done, note how you can still see the border between the desk and sandpaper.
