Iron Man Keychain

Inspired by futuristic energy cores and geometric symmetry, the ArcCore Keychain blends bold lines with layered depth to create a striking visual centerpiece. Designed with dual-extrusion or color-swap printing in mind, the recessed channel pattern pops against the bold circular base—perfect for showing off multi-color prints or filament transitions. At just 36mm in diameter, it’s small enough to be subtle on a keyring, yet detailed enough to turn heads. Comes with a built-in loop for easy keychain attachment or lanyard mounting. Recommended Print Settings: Layer Height: 0.2mm Infill: 15% – 20% Supports: Not needed Brim: Outer Brim (3-5 lines for best adhesion) Filament: Use contrasting colors for maximum pop (e.g., matte black + silk blue) 🔄 Print Time: ~40–60 minutes depending on speed ⚠️ No supports required if printed flat
