My own version of CSS (Main core module)

As if the idea came to me after a bad experience with the latest CSS, the most serious problem was the overall weight of the entire space station

This at the time of the docking, something caused me several problems, since the space station was very light compared to the AS-238 module, which in mentioning it, was heavier than the entire station, a small push and the station spin like it was nothing, So technically I gave myself the task of making a CSS with a heavier main module, so that the dockings are easier and without last minute problems.

As a player, I am very used to working with modules that are too heavy, so I hope and this does not cause problems for other people who download this sandbox. (150% docking ports)
