This is a very simple box with jumprings for hinges allowing the top to move back and forth yet stay attached to the rest of the box.
Step 1: BoM
Step 2: Outline and Fill
I started my box with an outline and then colored in the edges and kept going around and around in a steady line as best I could. It didn't always work. When all 6 sizes were done, I trimmed them and filled in any holes.
Step 3: Sides
I started with the bottom and then carefully attached the sides with more filament. I went around until all the sides were attached to the bottom piece as well as each other.
Step 4: Lid
I poked small, corresponding holes in one side of the box and the lid. Then I slid small jump rings into the holes and twisted them closed.
