About this 3D model

Inspired by a barrel-shaped piggy bank from many years ago, I drew this model to use the barrel as a pen holder. The assembly requires neither glue nor screws or nails, it is all to be assembled by interlocking. I recommend starting by placing the bottom, the lid, two slats facing each other and one of the large hoops to hold everything in place. Then all the other staves must be inserted one by one, finally blocking the entire barrel by inserting the other circles.
