Barrel!

Each of the bands are a separate piece to allow for easier painting, or if you want to print them in a different material than the main base. 
In my print I used the same filament (Bambu Matte PLA) for the whole thing and just finished/painted them. 

The bands are asymmetrical, so do a test fit of the middle bands both ways to see which you prefer. They should pressure fit just fine, but gluing them down is recommended if you want to handle it regularly.

As a completely optional step, I do also recommend lining the middle with felt or fabric of some sort. I used fabric glue to affix a piece of felt to some regular card stock cut to the shape of the interior, and then glued that card stock to the interior to make sure it was nice and smooth.
