Prompt
Design a functional 3D printable mechanical pencil body intended for real-world use and assembly. The model must be optimized for FDM 3D printing and designed with realistic mechanical tolerances. Structure: Create a cylindrical ergonomic pencil body with a total length of approximately 150 mm and an outer diameter between 10–12 mm for a comfortable grip. The interior must be hollow with a central internal chamber running through the body. Lead System: Inside the pencil body, design internal separated channels capable of storing and guiding three different graphite lead types: HB, 2B, and 6B. Each internal channel should be separated to prevent the leads from mixing. Each channel must support standard 2 mm graphite leads and include a guiding mechanism that directs the lead toward the tip for proper writing functionality. Tip Interface: The front section of the pencil must include a threaded connector (screw system) that allows interchangeable top modules designed for different lead hardness types (HB, 2B, 6B). The thread should be practical for 3D printing and assembly, approximately similar to an M8 thread or equivalent scale. Rear Section: The rear end of the pencil must include a removable cap. Inside this rear cap area, create a hollow cylindrical compartment capable of holding either a small circular eraser or a mini circular brush used to clean graphite dust. Design Constraints: Use a minimum wall thickness of 2 mm to ensure structural strength and durability. Include internal tolerances of approximately 0.2–0.3 mm so that parts can assemble properly after printing. Add subtle external grip textures or grooves along the body for better ergonomics. Avoid overhangs greater than 45 degrees to reduce the need for printing supports. Output Requirements: Design the model as separate printable components that can be assembled after printing, including the main pencil body, the rear cap, and the internal lead storage divider. Ensure all parts align correctly and assemble smoothly after printing.
