Locking nut for reloading tools and dies

After adjusting the depth of a reloading tool/die in the press, use this plastic locking nut to keep the metal/standard nut in the same place until next time.

7/8"-14 thread, fits most (all?) reloading presses e.g. Hornady, Lee, RCBS, Lyman...

I suggest printing in PETG with 100% concentric infill, for best strength. Not sure it matters much though - you will probably only tighten this thing by hand.
