This is a compact container for sewing thread bobbins in a 3x3 configuration that holds a total of 9.
It was designed to accompany my vintage Singer 201-2 sewing machine so one version of the top has the old vintage Singer logo and there's also a version without any logo. For the bottom, you can select a flush version for a seamless edge or a notched version that allows you to easily separate the top from the bottom.
This holds vintage style metal spools as well as the modern clear plastic ones.
Print the top with the flat side down (especially on a glass bed for a smooth and shiny top).
The lid is toleranced with an offset so that it should open and close without being too tight.
