I've been using gyroid infil almost exclusively since I first tried it.
I was using cubic before, which was fine, but gyroid seems much sturdier for the same % infil even if it does take a bit more print time.
Also it looks awesome.

This is PETG also - it makes for super sturdy prints.
4 walls 30% gyro infill. Strong as a rock.
Increase the extrusion width on the infil as well- it’ll print the same amount of material, butb juice the strength phenomenally. 150% of default (which is usually at or near nozzle width,) for appearance parts. 200% for strength
That's a good tip - I haven't tried that yet. I'll give it a shot next time I need something sturdy
It also speeds up infill printing (because it takes fewer passes, I’ve found.)
I can’t take credit- that goes to cnc kitchen
