air intake trumpet 3d model

Create a high-performance motorcycle air intake velocity stack (airbox trumpet) optimized for a parallel twin engine similar to the Kawasaki Z500. The model must be a smooth bellmouth intake trumpet designed to maximize airflow and reduce turbulence inside the airbox. Technical specifications: • Total length: 40 mm • Bellmouth outer diameter: 82 mm • Bellmouth radius: 14 mm smooth rounded lip • Internal throat diameter: 36 mm (matching throttle body) • Internal taper angle: 9 degrees gradual venturi transition • Wall thickness: 2.5 mm Geometry requirements: • Smooth bellmouth entrance with aerodynamic radius • Progressive venturi shape from 82 mm inlet to 36 mm throat • No sharp edges or abrupt transitions • Internal airflow surface must be smooth • Include a mounting base ring compatible with motorcycle airbox stacks • Base outer diameter: 60 mm • Base height: 12 mm • Include 3 locking tabs evenly spaced for airbox mounting • Add small internal structural ribs if necessary for print strength Manufactur
