but you could cut a nice outline out of 1/2" acrylic so that the device is always in the same spot.

But if you're primarily working with a limited number of shapes, then making pockets or cutouts in a piece of acrylic fixed to the table should be the most reliable. And you might not necessarily have to center everything. You could make an iPhone pocket toward one corner of your acrylic piece and know that any time you'll be engraving an iPhone, that the phone center will be at a known X and Y position on the table. Then you can position pockets for other items elsewhere on the same acrylic piece.
