The prompt
A parametric 3D CAD model of a Formula SAE 20mm Venturi restrictor. The model consists of a hollow rotationally symmetric body with an inlet diameter of 45mm, converging at a 14-degree half-angle down to a 20mm throat diameter. The throat length is 2.5mm with smooth 15mm radius fillets. It then expands via a diffuser section at a 4.5-degree half-angle to an outlet diameter of 55mm. Wall thickness is uniformly 2.5mm. Clean geometry suitable for CFD fluid domain extraction, exported as a solid body.
Parameters
| Name | Value | Range |
|---|---|---|
| Inlet Diameter | 45 mm | 30 – 80 |
| Throat Diameter | 20 mm | 10 – 28 |
| Outlet Diameter | 55 mm | 30 – 100 |
| Converging Half-Angle | 14 deg | 5 – 40 |
| Diffuser Half-Angle | 4.5 deg | 1.5 – 20 |
| Throat Length | 2.5 mm | 0.5 – 20 |
| Throat Blend Radius | 15 mm | 6 – 40 |
| Wall Thickness | 2.5 mm | 1 – 4 |
Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
