This is possibly are 5th Butterfly Knife, it is are strongest so far. it is also personally, one of our best. though, you might want to scale the knife accordingly. and smooth it out ounce printed.
I also recommend to in cura to change the thickness of the blade, to about .5mm smaller, so that it saves time smoothing it out later to make it fit. for printers that are larger and much better at printing, actually, this might not be a problem.
