thingiverse

The United States Bullion Depository, commonly referred to as Fort Knox, sits within the fortified walls of the U.S. Army post in Kentucky. This vault serves as a secure repository for an enormous portion of the nation's official gold reserves and occasionally houses other precious items belonging to or entrusted by the federal government. It is estimated that this vault contains approximately 2.3% of all the gold ever refined throughout human history.
