The prompt
Generate a 3D CAD model (solid body) of a standard disposable electrosurgical pencil electrode with blade tip. Output as STEP file (preferred) or STL mesh. All dimensions in millimeters. The model must be a single watertight solid, printable and manufacturable. GEOMETRY (origin at rear center of shaft, Z-axis along length): 1. SHAFT: - Cylinder, diameter 2.36 mm, length 70 mm total. - Rear face: 0.3 mm x 45° chamfer. - Shaft occupies Z = 0 to 70 mm. 2. BLADE TIP (Z = 55 to 70 mm): - Front 15 mm flattened into a blade: two parallel flat faces, thickness 0.6 mm. - Blade width tapers from 2.36 mm at Z=55 to 1.2 mm at Z=70. - Tip: 30° included angle at the very front (last 3 mm), sharp cutting edge on one side. - Blade bent upward 10° starting at Z=60 mm. - 0.1 mm fillet on all edges except cutting edge. 3. CONSTRAINTS: - Single solid body, no assembly, no internal cavities. - Symmetric about XZ plane except for the 10° bend. - Watertight mesh, no self-intersections, no floating parts. - Material: stainless steel 316L (density 8.0 g/cm³) for mass properties. 4. OUTPUT: - STEP file (AP214) if supported, otherwise STL (binary, 0.05 mm tolerance). - Include a simple front-view and top-view screenshot for verification. - Report bounding box dimensions and volume. ASSUMPTIONS: If any dimension is ambiguous, use standard electrosurgical electrode values (shaft 2.36 mm, total length 70 mm, blade thickness 0.6 mm) and note them.
