3D Postcard Stereograph Viewer

This little gizmo is used to view stereoscopic images on a postcard-sized printout. The centers of the two images should be 64mm apart for optimal results (that's the interpupillary distance this was designed for). The lenses I used were 35.5mm in diameter

Only one place needs glue: the interface between the viewer and the slider. Align the bottom edge of the viewer with the curve of the slider (make sure it's centered) and use strong adhesive to bond them together. Otherwise, just print and assemble... it's that simple!

Making your own 3D images is easy and fun! Just take a picture from a left eye's perspective, then the right... put them together and print out (they need to be small enough to fit within the focal range). Put inside contraption and re-live those old experiences like you never have before!

I know, I know... your life just got 20 times better... You're Welcome!! :)
