metal ring logo 3d model

Create a precise mechanical 3D model of a ring-shaped structural component. Specifications: - A circular ring (part 4) with uniform thickness. - The ring has a gap opening on one side (a deliberate notch). - Connected to the ring is a smaller circular hub section. - From the smaller hub, extend two parallel fork-like arms (part 3), with flat ends and proper spacing between the arms. - The structure must be rigid, symmetric, and geometrically clean. - No textures, no rendering materials — produce clean CAD-like geometry suitable for engineering. - Ensure all edges and surfaces are smooth and accurate for later editing in Shapr3D. - Output as GLB or OBJ.
