stone fist 3d model

Highly detailed 3D sculpt of a large stone fist with the hand fully closed in a tight clenched position. The hand must have exactly three thick fingers plus one thumb, no extra fingers, no visible nails, segmented knuckles clearly defined. Surface resembles cracked rock with deep creases and rough texture. The wrist is cylindrical with an engraved spiral symbol on the front, and a thick ring-like band separating the hand and forearm. Base is circular with carved runes and stone patterns. Designed for 4-color 3D printing: assign separate clean regions for colors (fist red, band dark red, base dark gray, engravings/spiral slightly lighter tone). No gradients, no color blending, sharp separations. Style realistic with fantasy elements, strong volume, deep shadows. Ensure solid watertight mesh, no thin parts, optimized for FDM printing.
