I am reposting this box since I think that I made the original files with Inkscape 0.48 and I have learned since then that there are compatibility issues with SCAL1 and MTC. I have fixed and successfully imported the layered file with lines for scoring in the current version of MTC and the single layer file (without score lines) in SCAL1. The files make a box that is 2×1.25×1.25 inches (not counting the ends) when the file is set to 4.5 inches tall.
I closed the box two different ways. The first box I closed by pushing in on each scored triangle and tying ribbon around the box ends. The second box I only pushed in on two of the triangles and used brads to hold the ends closed. Other options include using a strong adhesive or decorative clips or staples.
The download includes a layered svg for use with SCAL2 and a single layer svg. These files are for personal use only. Feel free to link to this post, but the files are not to be shared or distributed in any way.
Download the files from here.
