This is a professional 3D jewelry model of a tattoo cartridge needle pendant, designed with clean geometric surfaces and accurate proportions.The model has been hollowed internally to reduce metal weight while keeping the outer structure strong and production-ready.

The pendant captures the iconic shape of a tattoo needle—cylindrical body, ribbed grip, and tapered tip—making it ideal for tattoo artists, collectors, and custom jewelry makers.

Every surface is optimized for CNC milling, lost-wax casting, and resin 3D printing. The mesh is clean, watertight, and free from undercuts to ensure smooth manufacturing.
