It follows the same file names as the other worktable icons, "PlugType 1" for Furnaces, "PlugType 2" for Civil Cutter, "PlugType 3" for Basic Skiver, etc. "PlugType 6" is probably another type of worktable, unreleased at the moment. As far as I remember, that icon didn't exist in Alpha 2.0, along with the grinder and blender icons.

We'll just have to wait and find out what and where it comes from.
