Thunderstone Dragonspire Insert

This is a remix of szkryb's Marvel box organizer. I love the solution.

I had to add 9mm to the length to fix Thunderstone's box snuggly.

I also hexed the walls and base to save about 35% on weight. Much lighter now.


I used a brim only to prevent curling at the corners. It might not be needed with the holes in the base.
