Summary

This is an accessory for the excellent 4" Horn speaker:

You can clip or glue it into the horn mouth to cover the right sidewall in case you printed them in a different colour or use (like me) wooden sidewalls. With the plate inserted, you can no longer see the side wall from the horn opening.
