Adjustable Tobii Clip

A 3D Printable, adjustable, clip for holding a Tobii eye-tracker onto a laptop.

This clip is designed to accommodate laptops between the thickness of the 2021 M1 MacBooks and the Dell Latitude E7470.

Notes on Assembly and Usage

A video on how to assemble the eye-tracker clip can be found here. Written instructions can be found below.

Step Zero

Start the assembly with all the pieces laid out in front of you. The two long pieces are the clips, the two middle-sized pieces are the stoppers, and the two smallest pieces are are the end caps. Except for the end caps, the left and right sides are asymmetric.

Step One

Attach the stoppers to the rails of the clips. Thread the wire of the eye-tracker through the right clip before attaching the stopper.

Step Two

Attach the end caps to the end of the clip rails. Set up the eye-tracker at the bottom of your laptop display, with the eye-tracker visible between the clips has shown. The back of the clip should be behind the back of the laptop lid, holding it in place.

Usage

The stoppers can be moved to adjust for the width of your screen, so that the Tobii eye-tracker is always centered. The ridges at the back of the eye-tracker clip can be sanded down, clipped, or otherwise flattened to accommodate the thickness of your laptop lid.

Notes on Printing

Supports

In the default orientations the clips and the end caps require supports. The end caps can be orientated to print without supports, but it makes part of the connection much more fragile.
