ok, I've tested your mod and it worked as well as I am not happy with the looks of it
well my reason of why I am not happy to what it looks like is because it's nothing but just a simple block.
the best thing to do with your mod if you're still working on it is.....
add more features to it like, affecting vanilla or ordinary armor and has some sort of animation so when we use the block it would look like a ship full of compartments as armor.
just do more work with this and it'll be a best armor mod can be out there!!!
