Summary

Dispenser for butcher's string.
This is something to keep string clean with the bonus of preventing it from rolling away when it is used.

This fits the standard size kitchen string (as found in the USA anyway). At first it was a little difficult to get the string started. The trick is to put the end of the string near the hole with a little slack. Then sharply inhale on the top of the dispenser.

Two bases are available. The "plane" base doesn't offer much grip for unscrewing so I recommend the "fancy" version.

The CAD design is available on Onshape
