Cobra Commander (Resolute) Knee Pad Help!

[Hack Sparrow]

I am putting together a pretty screen accurate Cobra Commander costume from GI Joe: Resolute. I've found sources for just about everything I need, but I could really use some help with the knee pads. Does anyone know of anyone that could fabricate something that looks like these? Or where I may be able to find some that look close enough to the pictures? Thanks!

Those look like they'd be simple enough to make out of foam. Easy, basic shape and form, it wouldn't be hard at all do to yourself!
