Printing parameters: For printing the spring, I recommend using high-quality PLA, such as PLA Plus, PLA 850, or higher. This way, we can ensure it lasts longer. PETG can also be used. I recommend printing the pieces separately to achieve cleaner results. It's also important to avoid having the seams inside the guides to prevent unwanted friction. When printing the spring, I suggest increasing the temperature slightly higher than normal and ensuring good layer adhesion.

Enjoy printing!
