Extract chilling adaptor ring for - Sworksdesign Dripper

I bought a frozen ball holder to use with filter coffee brewers. Unfortunately I couldn't use the Sworksdesign dripper with it because of the size of the ring it sits on.

This is a pretty simple adapter ring so that the Sworks dripper can sit cleanly on it.

Included both STEP and STL, as always STEP seems to work better.
