King of Tokyo insert - Power Cubes remix

The original insert is very good, however I found that if the power cubes weren't carefully moved away from the wall, the lip on the lid would often catch making it harder to close the box. I have added a small inner lip in the bottom of the box to mirror that of the lid, so that no matter what the cubes cannot foul the lid any more.

No special printing required. No brim or supports required.
