wooden sand sifter 3d model

Create a clean 3D model of a rustic manual wooden sand sifter, isolated as a single object. The object consists of a stable tripod made from three long straight wooden beams leaning inward and joined at the top. Suspended from the top center is one circular sieve, hanging horizontally. The sieve has a thick wooden ring frame and a flat fine mesh screen stretched across the bottom. The sieve is supported by 3 or 4 thin tension ropes or metal wires evenly spaced and connected from the rim to the top joint. Show only this structure: tripod + suspended sieve. No human, no sand, no shovel, no rocks, no construction site, no vegetation, no extra objects, no text. Realistic proportions, functional engineering logic, symmetrical balance, handcrafted rough wood, simple joinery, clean geometry, centered object, neutral background. Optimize for full object reconstruction and 3D printing reference.
