The height of the barrel is determined by yourself (generally it shouldn't be too high).

2. Fold the barrel body back according to the edge of the bottom cover, and then stick it together with a sticker (stick it tightly), so that it is roughly half done.

3. Make a hexagon according to the size of the bottom cover, then use the perimeter of the hexagon as the length and width as the shorter one, and then surround it according to the hexagon and stick it with stickers.
