Funnel Diagram Sketch - Educational Illustration for Science or Engineering #1359470 (License: Personal Use)

This black-and-white line drawing depicts a funnel-like shape with a rectangular handle on the left and a wide conical body tapering to the right. Dashed lines inside indicate symmetry axes or potential fold/assembly guides, suggesting use in instructional or prototyping contexts. The minimalist style emphasizes form and function over realism.

Used in educational materials, engineering schematics, or DIY project guides where visual clarity and conceptual simplicity are key; matches user intent for learning basic lab tools, geometry, or paper-craft templates.
