So, a friend of mine wanted to cosplay Quiet, but she couldn't find a model of the knife to print.
I whipped this one up for her and decided to share it on here :D

I added several variants for different build volumes and skill levels.

Variant 1 - print this:
CombinedBlade.stl
Scale1.stl
Scale2.stl
Scalepin(x2).stl

Description: This is the entire blade combined in one. I suggest printing it with the spine of the blade on the bed. It will yield some overhangs, but if you don't mind either working those out or don't need perfection, this is fine. That's how the one in the pictures is printed

Variant 2 - print this:
Blade1Whole.stl
Blade2Whole.stl
Scale1.stl
Scale2.stl
Scalepin(x2).stl

Description: This is the entire blade split down the middle for printing flat on the bed. If you print it like this, I suggest either a small layer height or some very rough sandpaper to smooth out the bevels of the blade.

Variant 3 - print this:
Blade1_P1.stl
Blade1_P2.stl
Blade2_P1.stl
Blade2_P2.stl
Scale1.stl
Scale2.stl
Scalepin(x2).stl

Description: This is the blade split down the middle and seperated into two pieces. This is intended for printers with a small buildplate. It must be glued together after printing. If you print it like this, I suggest either a small layer height or some very rough sandpaper to smooth out the bevels of the blade.
