Attached is the piece you want from the Halo Archive discord server. This is a game rip, so it's not the highest quality. It is also not scaled properly. You will have to adjust the scale if you want to print it.
Here's how I retrieved it:
I've joined the
Halo Archive Discord Server
I downloaded the Halo Infinite Spartan Pack V1.2 (2.5 Gb)

I opened the spartan pack in blender and searched for assailer pauldron
View attachment 360196
copied the file into a new project
exported to .obj
View attachment 360197
opened the .obj in windows 3D builder and selected auto repair when prompted
View attachment 360198
saved as .stl
As I said before, this is a game rip, so may not be the quality you're looking for if you want to 3D print it. I hope it's helpful anyways!
