The name Claire in six different 5.5 inch (can be enlarged or reduced) patterns which can be assembled into a cube.  The inside edge of the outer border pieces need to be ground to a 45 degree angle so that the edges fit together in a mitre, rather than have one three panels smaller in dimension than the others so that the cube fits together without a lot of solder being needed in the corners.  However, if you are pretty good with the solder gun then you could avoide beveling the outer edges of the border and fill in the solder so that the 90 degree angle where the pieces meet becomes a 45 degree fill with solder with a little rounded edge.   No assembly instructions are given, just the six patterns, and knowledge of how to create a box with stained glass is found on many sites online.
