Design a 3D model of a dark and deadly science fiction grenade for use as a card game graphic. The grenade should have a menacing, high-tech appearance and incorporate elements of the aesthetic and technology of a gritty science fiction universe, such as Warhammer 40,000 or similar. The model should be highly detailed and rendered to look like it could be used in an intense battle or combat situation. The final product should be ready for use in a card game and be able to be placed on a card layout." | Anything
