A segmented body fragmentation hand grenade with cast grooves round and up the body, a knurled fuze, a striker lever and a pull ring on a split pin. Dimensions 0.069 x 0.113 x 0.061 m (X x Y x Z). Origin at the footprint centre, resting on y = 0; metre units, +Y up, muzzle and point toward +Z. Static ordnance: the striker lever, the pull ring and the split pin are modelled as separate solids but do not move, because a released lever and a pulled pin are two states of one linkage rather than a rigid node transform. Static geometry: no rig or animation. Blued gunmetal, bright machined steel, dark anodised alloy, black and dark earth polymer, rubber, walnut, brass, copper, leather, olive paint, optical glass, concrete and emissive red, green and warm white for reticles, lasers, tritium and lamps. Physically based flat colours with no texture maps. Original invented design: no real make, model, manufacturer or marking is represented. Free 3D model for Unity, Godot, Unreal, three.js and Blender. No collision or navigation data.
