3D Print of Dragon Ring / Drake Jewelry Pre-Supported / Draconic Accessory / Dragonborn Decoration / Draconic Artifact / Biker Deco

Hello, I bought this file a few days ago and I've just printed it. As you can see on the photos there is a part that is much too thin and breaks even before I put it on my finger, I see that on your photos this part is thicker and should be less fragile than on the one I printed, would you know what I can do to increase the strength of this part of the ring please?Print on Elegoo Saturne 4 Ultra
