Autostrut! The saver of many creations.
Autostrut is a system that requires you to enable "advanced tweakables" in the settings and it allows parts to be phantom connected to a common part as well as it's "parent" part it is physically connected to. This allows things to be very rigid without the need of physical struts and it is in the stock game.
