They developed the SOball for use with the JoyKey automatic water drainage system in close co-operation with Andrew Joy. The Soball collects the drops leaving a JoyKey. It lets you decide WHEN and WHERE to dump the water. The holes in the Soball can be positioned so that the water drains when the instrument is placed on a stand.
After replacing the original JoyKey O-ring with the white Soball O-ring, the Soball is then pushed over the JoyKey (see instructions on the YouTube video).The SOball is Made in Germany using 3-D printing.
