The prompt
Generate a precise 3D CAD model of a Monopolar HF Surgery Electrode (electrosurgical pencil tip) based on the following exact dimensions and features. The total length is 70 mm. The model must be a single solid body with three distinct sections along a central axis: 1. Rear Shaft (Tungsten): - Length: 16.5 mm - Diameter: 2.4 mm (cylindrical) - Position: Starting from the left (x=0). 2. Insulation Sleeve (PEEK, Blue): - Length: 25.5 mm - Outer Diameter: 4.0 mm - Position: Immediately after the shaft (from x=16.5 to x=42.0). - Features: Create 3 evenly spaced circumferential ribs (ridges) on this sleeve for grip. The ribs should be slightly raised (e.g., +0.3 mm) compared to the main 4.0 mm diameter. 3. Transition Cone (Tungsten): - Length: 10.5 mm - Position: From x=42.0 to x=52.5. - Geometry: A tapered trapezoid that starts at a circular diameter of 2.4 mm and smoothly transitions to a rectangular flat profile with dimensions Width = 2.3 mm and Thickness = 0.55 mm. 4. Active Blade (Tungsten): - Length: 17.5 mm - Position: From x=52.5 to x=70.0. - Geometry: A flat rectangular bar with Width = 2.3 mm and Thickness = 0.55 mm. - Tip Feature: The distal end (far right, x=70) must have a sharp bevel (cutting edge) at an angle of 15 to 20 degrees, tapering to a sharp edge. Visual & Material Details: - Apply a Blue color to the PEEK insulation section. - Apply a Polished Metallic (Tungsten) finish to the shaft, cone, and blade. - Ensure all transitions are smooth and the central axis is perfectly aligned. - The final output should be a single watertight solid model suitable for export as STEP or STL.
