Ipad 3 Magnetic Speaker redirector

I believe it will also work fine on an Ipad 2 but not tested.
Held on with 4 small magnets, self adjusting, takes a reasonable knock or simply slides off. Makes a HUGE difference in audio.
Prints flat in 2 parts with no support needed, there are no overhangs.
I have tried a few out there and they were all a pain to print and never attached properly.
