Toy ring collection v2 3D print model

Blender 3.1 Clud ring Crown ring Butterfly ring Diamond ring Sun ring I prepared two types of rings. closed O with an internal diameter of 15mm. And flexible type C with a similar diameter. All elements were printed with a 0.4mm nozzle. I recommend printing with a layer height of 0.12 and 100% infill. For safety, the elements should be glued together.
