bidet spray handle 3d model

Subject: 3D Design for High-Pressure Bidet Sprayer Handle (Engineering Spare Part). Role: Expert Industrial Designer & 3D Printing Engineer. Task: Generate a precise, watertight, and functional 3D model (or Blender Python script) for a plumbing replacement part based on the attached reference image, with the following strict technical specifications: 1. Functional Specifications (Critical): Application: Bidet Sprayer Handle / Bathroom Shataf Head. Operating Pressure: Must withstand high water pressure of 8-9 Bar. Constraint: Wall thickness must be uniform and robust (minimum 3.0mm to 4.0mm) to prevent bursting under pressure. Inlet Connection: Standard 1/2 inch BSP (British Standard Pipe) Thread. Detail: Male thread geometry must be accurate for plumbing fittings (approx. 20.9mm major diameter). Fluid Dynamics: The internal channel must be fully hollow and continuous. Outlet Nozzle: The nozzle tip must have a tapered/constricted opening. Goal: Create a "Venturi effect" to increase water velocity an
