I recommend PETG with (at least) 3 Perimeters.
After struggling with the original Adria Adora curtain clips, which were too flimsy and kept breaking, I decided to take matters into my own hands. I've designed a 3D print model that's far more robust and durable than the original. I can attest to its strength and longevity. No more worries about unexpected breakages! Upgrade your Adria Adora curtain experience with the model I've created just for you.
The author marked this model as their own original creation.
