four-pestle dhiki 3d model

Create a highly realistic and mechanically accurate 3D isometric industrial model of a 4-pestle electric dhiki machine used for agro-processing and grain pounding. The machine must look like a real workshop-fabricated industrial machine, not futuristic or artistic. The overall appearance should represent a practical engineering design suitable for manufacturing in a rural or small industrial workshop environment. The machine uses a vertical reciprocating impact mechanism driven by a rotary crank-slider system. The design must clearly show how rotary motion from an electric motor is converted into synchronized vertical up-and-down motion of four pestles. The machine frame is made from welded mild steel square and rectangular hollow sections. The frame should appear strong, rigid, and capable of handling repeated impact loads and vibration. Use realistic industrial fabrication details including welded joints, gusset plates, support braces, mounting plates, and structural reinforcement.
