SimpleCBM

The Common Berthing Mechanism (CBM) is the standard connection system used to structurally join large pressurized modules of the orbital segment, such as permanent modules or cargo vehicles, allowing for the transfer of cargo and crew with more space between the modules due to its large diameter.

You can use it to place between the modules of your station. This is a simple version and is not 100% accurate to the real model. However, it will allow you to use it easily and more practically if you want to build modules with an interior.

I also added a very simple door to a pressurized group, so that you can add it to your module without worrying about that. Use Slider 1 to lower the door.
