need a little advice on ABS wall thickness for my first project.

I have done some rough calculations to estimate the potential stresses on my holder. Assuming that the internal structure of my eye tracking camera is relatively even, I would say that the density is approximately 1.7 g per cubic centimeter or 1 oz per cubic inch. If you noticed an earlier comment I made in this thread, I posted a link to a tablet holder on thingiverse. The main weight-bearing support sections of the tablet holder are only 1.5 mm thick and the distributed weight of the tablet is significantly greater than my eye tracker. That leads me to think that 2 mm would be enough for much of the cradle.
