On screen stereo viewer

Step 3 Building it

Cut the glass. the outer pieces should be as large as possible. I made them stick out of the box. Instead of making them rectangular, a trapezium shape would be better (wide ends on the outside). Next time better.

Cut one of the boxes diagonally. make a hole or slit at the bottom in the middle (see picture). This will serve as the mirror holder for the central part, towards the eyes. The lid of this box is not needed.

The screen side of the other box, which should be quite elongated, has to be cut in order to allow the view on screen to enter the box. Best is to take the mirrors, hold them in the proper position, and draw the line where to cut. The lid has to be cut in a similar way. The holes for the eyes have to be made as well

To support the outer mirrors, 2 pieces of wood have to be glued inside the box at 45 degrees (eye side). The mirrors can be glued on the wood with silicone putty.

I fixed the outer mirrors in the box, the inner mirror holder is bolted on the lid. Some play back and forth might be handy.

The picture shows the lid upside down behind the body.
In order to clean the mirrors I did not glue the lid on the body
