These are the knee joint covers for the Iron Man mk IV and VI suits!
Created from reference photos taken from Iron Man 2, these buttons will add the extra details in the suit that will really help bring your suit project together. The parts are made at 0.75mm thicknesses so reinforcements may be necessary (you can fill the parts with Smooth-On's Freeform Air epoxy putty to save weight). The thinness was necessary to reduce costs as much as possible.
One order will include all 4 knee joint covers so you don't need to order multiple times!
