Custom Chest Size lets you expand your chest inventory up to 8 columns and 20 rows, all while keeping the sleek interface with a built-in scrollbar.
This only affects newly built chests.
This was taken from Nexus and put onto thuderstore for making server modspacks easier share.

This mod should be installed on the server and all clients otherwise items in the extra slots can potentially be deleted.
If your settings are not the EXACT same as the server you are on, the server will probably delete the items.
While Settings can be adjusted in game on the client, I do not know if they will also update server-side while the server is up, so its best to set the settings on the server config file then restart
CustomChestSizeMod.dll into <GameDirectory>\Bepinex\plugins.
