Modular Snap-Fit Ball Joint Fidget Chain

Boost Me

This Modular Snap-Fit Ball Joint Chain is a high-performance mechanical system engineered to print completely support-free and work immediately after printing. Featuring an optimized ball-and-socket design inspired by the geometry  each individual link snaps together with a highly satisfying, crisp tactile click. The integrated vertical flex-slots allow the socket walls to temporarily expand and safely capture the next link, resulting in a fluid, multi-axis range of motion capable of twisting into striking multi-color arches.

🚀 Key Features

• Infinite Linkage System: Print as many links as your build plate can hold and snap them together to create endlessly customizable configurations.
• 100% Support-Free: The organic curved geometry self-supports perfectly during printing, saving you post-processing hassle and material waste.
• High-Flex Articulation: Engineered with built-in wall cutouts that allow maximum angular bending without popping the chain apart.
• AMS & Silk Filament Optimized: Designed to look stunning using dual-tone, tri-color silk, or standard matte filaments.

🖨️ Recommended Print Settings

• Layer Height: 0.20mm Standard (or 0.16mm for maximum joint smoothness)
• Wall Loops: 4 Perimeters Minimum (Crucial to give the expanding socket walls the elastic strength they need to prevent snapping during assembly)
• Infill Density: 20% to 25% (Gyroid or Grid)
• supports: None / Disabled
