This is my improvement on my own design http://www.thingiverse.com/thing:3915V1 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.Video of it spinning around: http://www.youtube.com/watch?v=u0XMJx0voJU Video of the lids being printed(before I made lid thicker): http://www.youtube.com/watch?v=-ZDZ3nH7UgoGetting the pieces: 1) Print all parts(make sure oozebane is properly calibrated or Center Shaft and Lids will not print correctly 2) Remove the extra plastic on the Lids that exceeds the boarder of the heart halfs. 3) Cut off the 2 thin rings on Lid and Center Shaft that hold up the top. 4) Carefully file or cut any bumps that exceed the model design and make sure all the parts fit together. There is 0 clearances in this model. this is done so you get a nice snug fit.Assemble the box in the heart orientation: 1) Glue the bottom and middle left pieces(pieces that slide together from the top) together with the Center Shaft trapped between them(do not glue the shaft). 2) Place the Right heart lid in the other pieces so it is in the fully open position. 3) Put the Left lid together with the Right side bottom piece in the same fashion 4) Place the pieces put together in step 3 around the center shaft and slide the Right side Middle piece in place(with some glue to hold it there permanently) 5) Place a picture in it and rotate the lids around to the closed position then rotate the 2 halves so it becomes a pendent.
