Tobii Pro earpiece clips

thingiverse

These are snap-on ear piece clips designed to fit the Tobii Pro 2 eye-tracking glasses. Snapping these onto the frame of the glasses and wearing them over the ear will adjust the angle the eye-tracker sits on the face of the wearer. This is beneficial during rifle marksmanship tasks when the Tobii's front-facing camera would fail to adequately capture the shooter's gazepoint.
