  • Patent number: 12508410
    Abstract: A moldable gripping device for use with a tattoo machine includes a tube and a Room Temperature Vulcanization (RTV) silicone rubber. The tube has a first end, a second end, and an outer surface. A tattoo machine can be inserted into the tube so that the tube is removably secured to the tattoo machine with an operable end of the tattoo machine protruding from the first end of the tube. The RTV silicone rubber comprises a first part and a second part, which are mixable to form a substrate. The substrate is moldable to the outer surface of the tube, deformable by grasping in a hand of a user, and curable to form a custom molded grip. The custom molded grip is substantially nonpliable and is molded to fit the hand of the user.
