N-Type socket hood

The N-Type sockets can be found on many devices with RF outputs/inputs. In order to protect these sockets from mechanical damage and dust when they are not used for a long time, I have designed this cover.
A simple cover to put it on loosely wasn't ideal in my opinion. Since I don't expect this part to be exposed to high temperatures, I have decided to use PLA as the printing material.
When designing the 3D model, I took into account that this material also shrinks slightly when it cools down.
The model has a slightly larger inner diameter than the socket itself. Inside it has 3 edges in which a thread is cut when it is screwed on for the first time. During this process, you should therefore make sure that the cover is screwed on straight.
By design, I have tried to make it sure that this process is very easy and almost completely effortless. The 3 edges are therefore not cut particularly deep. One of the images uploaded here is a microscope picture of one edge after it has been sc
