The plans for the laser cut portions of the rig are provided in Adobe Illustrator format. A full parts list along with assembly instructions and a guide to image acquisition are also included. Note that this rig was designed for materials that are available in the United States. Adjustments may need to be made for use with metric materials.This simple and inexpensive rig is designed to assist researchers in capturing photographs for reflectance transformation imaging (RTI). It consists of 3D printed and laser cut parts, along with relatively easy to acquire hardware components.
