This is a template from SU. It measures:
* 5 and 2/8 inches wide
* 3 and 1/2 inches tall
* 2 and 7/8 inches deep
Since I can't leave well enough alone, I modified it to be directly printable. I like to have no dotted lines (just little marks that show you where to score. There's a score guide version available too...)
The only way I could figure out how to make this SU template assemble (there were big gaps in the side panels) was to add side panels. It's super easy:
1) Create side panels (cut to measure 2 and 7/8 inches by 3 and 5/8inches.)
2) Dry fit & trim them if needed
It seems a pain but it's actually kind of neato since you can stamp, emboss, and/or embellish the side panels if you like & cut some to line the box as well...
