Container with a through-hole

This is a container with a through-hole.

I use it as a weight for the bottles as I make PET plastic strips to make filaments.

Inside the container you can put sand, stones or other things as a weight. And you can put as much as you want depending on the weight to be made.

The hole in the center allows the rod that holds the bottle to pass through.

I have included the source file in FreeCAD in case you want to modify it.
