Audio Jack Fixture (customizable)

thingiverse

This is a customizable thing to prevent your off board audio jacks (6.3mm or 1/4 inch) from rotating inside a metal housing and short circuit other metal parts.I believe it doesn't work for all the connector types, but if you have a similar one you can try to customize it to your needs.You can easily adjust both external size and form to make it abut into the enclosure's walls and internal features to fit your connector variance.It has to internal features: outward and inward . The outward one is for the main contact which protrudes outward. The inward one is for the ground pin which has a small groove.It leaves the ground contact open, so the connector still has contact with the metal box.
