Flexi Keychain

🛠️ Ultra-Durable Flexi-Keychain | PETG Edition 🚀

The indestructible companion for your keyring!

Are you looking for a Flexi model that won't break the first time you sit down with it in your pocket? This articulated keychain has been specifically optimized for printing with PETG. While conventional PLA prints are often brittle and soften with heat (e.g., in a car in summer), this version offers the necessary toughness and thermal stability for real everyday use.

✨ Why this model?

• Maximum Durability: Thanks to PETG, the joints are extremely tear-resistant and easily withstand daily "fidgeting".
• Outdoor & Car-Ready: Does not deform in sunlight and fades less.
• Perfect Haptic Experience: The links slide together smoothly as silk after the first "break-in" – the ideal anti-stress gadget!
• Reinforced Eyelet: The ring connection is extra solidly constructed to keep your key secure.

🖨️ Print Recommendations (Tested on PEI)

The model is Print in Place, meaning it is printed in one piece and requires no support.

• Material: PETG (recommended for maximum stability).
• Plate: Textured PEI plate (creates the brilliant finish you see in my photos!).
• Walls: At least 3-4 to make the internal joint pins solid.
• Infill: 15% - 25% (Gyroid or Adaptive Cubic).
• Layer Height: 0.2mm (Standard) or 0.16mm for an even smoother movement.

💡 Pro Tip for Makers

If the links are stiff after printing, gently bend them in all directions once. Due to the flexibility of PETG, the hinges will "pop" free and then run smoothly as butter.
