Low Vision Small Goniometer

A request from an OT professor for a student with low vision that needed assist to read the small goniometer. It uses a small credit card size Fresnel lens that is cut down to fit the frame. (2 1/4 X 1 5/8 inches). Friction fit that gives the options to slide out of the way or leave it over the dial. There is a small recess that holds the the lens in place that needs to be cleaned out as well as the slot that fits over the gonimeter arm. Printed at 50% infill for extra strength.
