3.5mm jack plug
thingiverse
The design that this is remixed from causes the computer to think that there is a device plugged into the jack when in reality it's just the plug. This design makes the base a little taller so that the plug still goes into the jack enough to stay put, but not far enough for the computer to recognize that something is plugged in.
