Smartphone Stereographic Mount

Overview:
A mount that enables users to take 3D stereographic photos with a smartphone. See included example photo.

Background:
Stereographs are a set of two similar pictures taken at slightly differing positions to provide "parallax," the perspective difference between the two photos. This parallax, when viewed through the correct viewers, makes the brain think it is seeing an image in 3D! Usually, these photos are taken 65 mm apart, to simulate the average interpupillary distance (the distance between the eyes). Stereographs first became common around the American Civil War, and many early stereoscopic pictures can be found from that era.

Printing Notes:
Both the "Carriage Rail" and the "Phone Carriage" parts are needed.

This nut should thread onto most camera tripods, can can be found at local hardware stores. Once all parts ar
