Simple Curtain Hook

One of my curtain hooks vanished, and I could not find a similar model online. Thus, I took a photo, some measures, and made a simple approximation in Blender, to finally end up with a hook that fits snugly. I attached an image to compare the original (left) with the printed version (right). I printed in PETG transparent with 60% infill, though the model is so small and simple, such high amount of infill may not matter that much.
