hardware is unmeasured; check thread engagement and leave the hook free to turn.
The magnets close the unloaded fold; the open stop and pin carry the bag load.
There are no separate ear pieces or tiny eye plugs. For the proposed dark-eye
finish, add a small amount of matte near-black paint to each blind well floor
before fitting the face. This is a finishing consumable, not a third filament
requirement. Unpainted holes will reveal the head material. No purchase or print sent.
