Parametric mold for TRS jack sheath

NOTE
This thing is kind of weak; a 90 degree jack holds up much better. Check out thing: http://www.thingiverse.com/thing:882792 for a stronger version.

Create a customizable two part mold for casting a silicone sheath for a headphone jack. This can be used to create a mold for any size TRS style jack sheath.

When your favorite headdies need a new jack, tear it apart, solder on a new one and then cast your very own customizable sheath around the soldered mess.

See the instructions for customizer variables.
