For now the grill is just a texture. However, I've always loved the idea that you can see the pipes and such underneath it. Look at my first version of the system in one the
first page of this thread.
What I could do is to make the holes go all the way true, with the floor tile being hollow in the bottom. That way it could be used as normal. However, I could then at a later time make a component with pipes and such on it that can be shoved inside on the bottom of the normal floor tile.
One thing that might be tricky is the casting of the grill component, this because that part is 0.5mm wide. This means it is rather printable, but also quite frail, which might mean it will get damaged a lot. Would need to experiment a bit here...
