Create a 3D-printable **55 mm blobby fidget coin**, approximately 6 mm thick. Design it with: * A **soft, rounded, blobby shape** instead of a perfectly circular coin * A 55 mm overall diameter * Smooth, inflated-looking edges * Lots of **rounded bumps** around the outside * **Curved grooves** across the front and back * Different-sized bumps and grooves for a satisfying tactile feel * A soft, raised center area * No sharp edges or points * One solid connected piece * Easy to print with FDM 3D printers * No supports required * Flat underside * Clean, watertight STL geometry Make it look like a **soft, chunky, blob-shaped fidget coin** with exaggerated rounded bumps and smooth grooves. It should feel fun and satisfying to spin, rub, and hold.
