This is the cone greeblie for the x-wing pilot and tie pilot chest boxes. It comes with a threaded bolt for you to attach everything together. You'll be able to mount the cone centered, or off-center by using the two mounting hole positions in the disc. The knurled cone and flat disc are both precision machined from 6061 aluminum.
Adding a drop of locktite thread locker will secure the parts together so you don't lose anything while trooping!
