How would you print this with as little infill as possible? It's a wall designed to be knocked over so light weight is better.
I was thinking some sort of variable infill as it looks like only the top needs support really, but I can only see an option for variable layer height.
5% / 10% infill leads to quite a lot of bridging infill at the top which may or may not work.
Try using PS2.3 adaptive cubic infill option.
Alternatively try something like this attached 3mf project file.
Thanks I tried this but it didn't appear to make any difference at all - just infill from top to bottom at same %
Just saw your second post I'm going to give that a go, thanks
May be stating the obvious but you're not limited to setting infill to 5% steps. You'll need to pick infill pattern carefully eg gyroid at 1% provides no support.
Plus remarks by other posters, variable infill will raise the center of gravity, thus falling over easier.
