The prompt
Create a simple, realistic **3D-printable pencil model** suitable for an FDM 3D printer. Requirements: * Make a complete pencil with a **hexagonal wooden-pencil body**. * Add a **sharp pointed graphite tip** at one end. * Add a **small eraser** at the opposite end. * Add a thin **metal ferrule** connecting the eraser to the pencil body. * Keep the design as **one clean solid model**, with no floating or disconnected parts. * Use simple geometric shapes so it is easy to print. * Avoid extremely thin details or fragile parts. * Make the pencil approximately **150 mm long and 7 mm wide**. * Keep the graphite tip strong enough for 3D printing. * Make edges slightly rounded/chamfered where appropriate. * Design it so it can be printed without excessive supports. * The final model should be suitable for exporting as an **STL file**. * Keep the design clean, beginner-friendly, and easy to modify in Tinkercad.
