A small, collectible model in the shape of a sentry bot. Though this item appears in Fallout 4, its design is based on the sentry bot from Fallout 3 and Fallout: New Vegas, a trait shared by most collectible models in Fallout 4.
- Completed models can rarely be found in Vault-Tec lunchboxes.
- In O'Neill Family Manufacturing, when opening the sentrybot model kit.
- Automatron (add-on) In the Mechanist's lair, next to the drawing of the Mechanist.
