I’m printing some Gridfinity bins for some drawers, and one of them needs to be quite tall to fulfill its purpose (18u, ~130mm). I took a shortcut and generated one from this generator using the default wall thickness and printed using Prusament PLA. This resulted in the walls falling in on itself, and my second failed print.
In hindsight, considering the wall thickness of 0.95 mm, this seems pretty obvious to me now. I want to give it a second go, but beef up the wall thickness and make sure there’s some proper infill between the outer walls to keep it stiff.
At the same time I don’t want to waste too much filament, so I want to hit a sweet spot of sufficiently thin walls and sufficiently low infill percentage, while avoiding another failed print.
Anyone have good experience with these kinds of prints that could give some input on a rough estimate for what I should aim for here?
I am using Adaptive Cubic infill by the way, but for no other reason than that has become my default infill pattern after some previous suggestions made here.
I can’t speak for gridfinity bins in particular, but wall thickness can vary wildly depending on the purpose or look you’re aiming for. For medium-sized container (about the size of a closed fist), i would consider 1.50mm quite thin and wonky (but strong enough), 2.50 a good, solid width, and 4.00 quite chunky.
You can just print a few walls using the slicer and see what feels good, which is what I’d actually recommend you do.
Edited to add decimals
You want a 100mm box to have walls 25mm thick?
What are you trying to store?
