iPad2 sound shell
thingiverse
a mashup from two other things: seashell - http://www.thingiverse.com/thing:417402 ipad sound - http://www.thingiverse.com/thing:16140 I added a "spring" inside so this should fit with and without a cover on your iPad2 and later. If it fits iPad earlier, let me know. Added a second one that has a thicker shell which prints more easily.
