Is this a new feature request?

Just saw the Concept of "ribbed vault infill supports" aka "lightning infill supports" This seems like a great feature to add.

@rtyr looking at the pictures it‘s more about infill than (outer) support structure.

You are right, I was too quick with the labels.

@dartrax Yes, infill supports. I've added some additional text to clarify.

This is basically the ideal version I was envisioning. For supports, instead of infill, they'd only need some other options to let them work as removable supports, like:

Ribbed/fin supports ->

1. -> Bottom joint height (maximum height of fins to bond to the object wall)
2. -> Bottom joint distance (distance from wall, default .1mm, to allow fins to bond but be removable)
3. -> Rib non-bonding distance (distance from wall-to-rib for the non-joining parts)
4. -> Rib-top distance (Two options: Defaults to the Support Z and XY distance, or we can just use those, and not have two options here)
5. ... not sure what else would be good here.
