.50 Caliber BMG Keychain

thingiverse

This is a multi-part assembly of a .50 caliber BMG round transformed into a wearable keychain or pendant, scaled down 60% from actual size since a full-sized round is too large to be worn comfortably. The interior of the round is hollowed out and functions as a concealed compartment. Each component is designed with threads for seamless mating.
