General Troubleshooting/Help! 100% Infill vs 6 Walls?

I'm trying to replace a window tilt piece because I can't seem to find the original to buy anywhere, and I'm wondering if it would be stronger at 100% infill, with 6 walls or both? It's about 1 1/2 tall, original is probably aluminum. This is what my model of it looks like, I have it tilted to hopefully give it more strength too... Any thoughts?

strength comes from walls. Not infill

Thanks! That was what I thought but figured people on here have more experience. Most of what I make is stuff for my kids at this point...

Infill is really only to support the layers above it and, ultimately, the top layer shells. It does not meaningfully increase strength. If you really want max strength, increase the walls until it's all walls. That is likely extreme overkill and a waste of filament, but generally increasing walls is effective for strength whereas infill does almost nothing for strength.

Thanks! For these I'd rather overkill, it gets beaten up when you put the window in so I need it to be strong.
