Bring your desktop to life with this Modular Articulated Caterpillar! This isn't just a static model; it’s a high-quality mechanical toy designed in professional CAD software (SolidWorks) with real-world 3D printing tolerances in mind.

Each segment features a robust Pin-and-Socket connection that is both strong and flexible. Whether you want a short desk companion or a long, winding caterpillar, the modular design allows you to snap together as many segments as you like.

Engineering & Design Highlights:

Heavy-Duty Joints: Features a reinforced 6mm neck and a 4mm thick locking disk, ensuring the connections won't snap during assembly or play.

Precision Tolerances: Designed with a 0.4mm total clearance (0.2mm per side) for a perfect press-fit feel—smooth enough to move, tight enough to stay connected.

Flat-Base Optimization: The bottom of each segment is flat to maximize bed adhesion and simplify the printing process.

Charming Aesthetic: A friendly, minimalist face with a smile that looks great in any color.

Technical Specifications:Joint Type: Cylindrical Tenon with Circular Locking Disk.

Neck Diameter: 6 mm.

Locking Disk Thickness: 4 mm.

Total Clearance: 0.4 mm (optimized for FDM printers).

Scale: Easily scalable (recommended 100% for best joint performance).

Print Settings (Optimized for Quality):Orientation: Print segments flat on their bottom.

Supports: Minimal Tree Supports recommended. Only a tiny amount of support is needed under the joint's locking disk and the head's overhang to ensure a perfect surface finish.

Infill: 15-20% (Gyroid or Grid).

Walls: 3-4 perimeters (This is important to make the 6mm neck solid and durable).

Layer Height: 0.16mm - 0.2mm.

Material: Works beautifully with PLA, Silk PLA (for a shiny look), or PETG (for extra durability).
