Thanks to brettmcgin for a fantastic insert design. I'm not sure if anyone else has an issue with a little bit of "wiggle" between the insert and the top and sides of the box. Not enough to disrupt the organization, but my internal sicknesses will not allow me to sleep as long as the wiggle persists.

I concocted two braces that eliminate the wiggle. LeftBrace should slide outside the spy compartment, while UpperBrace goes across the top of the box. Recommend printing both upside down.
