What would be the most effective way to support the top layers of a cube

Hi,

I'll have to print a few models I've found on Thingiverse (dice towers)  for my son and I'm looking at the better way to support the floor.  In a nutshell, just imagine you want to print a cube...

Would there be a way to generate an infill which might look like a tree: a few trunks touching the bottom inside portion of the cube growing branches to nicely support the top layers of the cube.  Being able to do something like this would be a lot faster and economical while still giving a good support for the top layers.

I know with PLA I've been able to print a cube with basically no infill but I have to use PETG which, so far, is not as good with overhang...

 

Thanks for your help and suggestions

Play with "Infill | Gradual Infill Steps".  You can start with your regular infill at 10% and that Gradual setting at 4 and the Infill percentage will increase as it approaches the roof giving good support to the first layer above the infill while leaving the lower area with sparser infill.

This is exactly what I was looking for.

Thanks for your quick response!
