Piston Keychain

Hello!

Today, I’m excited to present a keychain design in the shape of a piston with a connecting rod, created especially for automotive enthusiasts. This model is 3D printed with PLA, ensuring durability and a sleek, modern look. Its compact size makes it perfect as a keychain, backpack accessory, or a stylish decoration. It also makes a unique and thoughtful gift!

The single-color version prints in under 9 minutes (excluding printer setup time) and is designed to be printed without supports for a smooth and hassle-free process. This project includes two versions:
🔹 Single-color – a classic, quick print.
🔹 Multi-color (printed per object) – allowing customization of different elements for a personalized touch.

For assembly, a small drop of glue is required to securely attach the piston and connecting rod.

Feel free to download and experiment with your own color combinations! 🚗🔧
