I don't know what the minimum thickness is that I could get away with. I did find this tablet holder for a galaxy tablet: http://www.thingiverse.com/thing:395373 and the main bottom section is only 1.5 mm. That makes me think that 2 mm would be just fine for my device. I just don't know how strong ABS is, not having done this before.
