Illusionist Buterfly Locket V2

This is my improvement on my own design http://www.thingiverse.com/thing:3915

V1 of the design could fall apart when the box was rotated 90 between states. This version fixes that but since the instructions are completely different and it is more work to assemble I made it a variant.
