Project Description: I have an existing 3D design project consisting of a main model and several individual component parts (provided in a .rar archive). I need a skilled 3D Modeler to: Extract and Review: Audit the provided STL files (Main model + "parts" folder). Assemble/Merge: Correctly align and merge all individual components into one unified, watertight 3D model. Cleanup: Ensure there are no overlapping faces or non-manifold geometry. Export: Provide the final result in a single [Insert Format, e.g., .STL, .STEP, or .OBJ] file. Required Skills: 3D Modeling, CAD/CAM, STL Editing, Product Design.
