3D Systems i Sense Bracket for iPad Air The i Sense Bracket from 3D Systems snaps onto your iPad Air to position your i Sense 3D Scanner for use. This is the same bracket that comes with your i Sense scanner, & can be used as a replacement part. This bracket is especially useful when you upgrade to a different model iPad: instead of purchasing a new i Sense scanner, simply affix the compatible bracket to your new iPad, & continue using your scanner as before.
