About this 3D model

Here is my model of bag closing clip with screw cap, there are already several similar models but I wanted to create one that met my needs. I stiffened the clip structure to seal better and added a gasket on the watertight cap. To join together the two parts that form the clip I used a M4x20 stainless steel cylindrical head screw with low self-locking stainless steel nut. Among the models there will be both the cap with the predisposition for the gasket and the cap without gasket. I also add the cap that says oats.
