Good lord no. Don’t do that. That would be a waste of filament and also cause a host of other problems for you.
Just to be clear, it is the “hoping to use infill to get some support” that your response is aimed at, right? Out of curiosity, what kind of problems could I be looking at for this?
In the meantime, I’ve been printing some smaller bins of about half the height of my problem where I increased the wall thickness of the model from the default 0.95 mm to 2 mm, and used 3 perimeters, which resulted in fairly sturdy walls.
Looking at the same bin with 2 mm walls without infill, and 3 mm walls with infill, there is barely any difference in material usage.






Yeah, this is what happened in the original, failed print.
I ended up making the model with 3mm thick walls, using two perimeters and 10% adaptive cubic infill (I sliced with gyroid as well, but it looked weird). Turned out great. I made some that were not quite as tall as well, with 2mm thick walls and 3 perimeters, which worked fine as well. It might have worked for the main boss here as well, but I’m not quite sure. The difference between the models was about 55 mm in height. The difference in material usage between the two options was negligible (< 10 g), with the infill variant coming out slightly lower in consumption.
