Sorry, I haven't gotten to the rest of the design yet. The eye tracker camera will sit completely flat in the cradle. However, it needs to have a 17° angle. To achieve that angle, the whole cradle will be sitting on 4 wedges (same material). Finally, the wedges will be sitting on a rectangular plate that will be velcro-ed down to a plastic tray that I already have. The cradle, wedges, and rectangular plate will all be one piece. For the most part, the tray will be rotated up by 90° at a vertical orientation. I might also need to completely flip the tray to an upside down horizontal orientation with the cradle facing downward (I am also going to add a Velcro strap to the front of the cradle to hold the tracker in.) I'll try to make another image if I have not explained this well enough.
