The 3D Printed Articulated Skull & Spine Keychain is built around one simple idea: take a compact skeleton-inspired design and make it move.
The linked skull-and-spine sections give the piece a flexible, fidget-friendly feel while keeping it small enough for keys, backpacks, bags, or everyday gear.
Why PETG?
For this keychain, PETG is a practical material choice because it offers more toughness and heat resistance than standard PLA. That makes it a better fit for an item that may get tossed into a pocket, clipped to a bag, or handled throughout the day.
What makes the design different?
The articulation is the whole point. Instead of a rigid flat keychain, the connected segments move independently, giving the spine a natural flexible motion and turning the piece into something that is both decorative and fun to handle.
Made one at a time
Each keychain is 3D printed by Printed Addiction. Small layer lines and minor surface variations are normal with the process and are part of what makes each finished print slightly unique.
