After seeing a couple of people talking about the correct way to do this I made a calculator to simplify the process and hopefully demonstrate the goal.
All you need to do is add the height of your object and the base you want to use and it will tell you if it will work or not and the setting to use in the GF, if it won’t work it will tell you why. If you don’t have a base in mind just put 0 and it will give you the minimum needed.
