Frosthaven Item Box

I liked the original design but I needed a lid. I also made some edits to make it more slim and to accommodate my needs:
- Made the walls thinner
- Took out the "Items" text on the bottom as you'd never see it and I wanted to save filament so I made it a hole
- Made it 5mm taller to accommodate potential item dividers based on armor type (e.g. helmet, hand, chest)
- Made it 8mm longer to accommodate the potential dividers as well as include Gloomhaven item cards (a few of which you can import to Frosthaven)

The lid is a snug fit. It won't fall off. It only has .3mm clearance on each side so it could probably have been a little less tight but you can still remove it relatively easily.
