Travel Box for Board Game "Splendor"

One of my favorite board games is Splendor, by Marc André. For a game which requires very few components, that box is rather large, so it's difficult to tote around. I've reduced the footprint and provided a sturdy casing to survive many years of being shoved into backpacks, taken on camping trips, biking and any other activities.

The print uses a simple lid, which uses grooves to stabilize itself laterally. Two rubber bands can be used to keep the lid secure.
