Here is my first model for a space marine pauldron. I wanted to make it look like it just went through a WAAGH! Unfortunately I dont own any space marines, and as such I cant scale this bit at the moment to perfectly fit an intercessor. If you are able to please leave the dimensions you printed at for others, it would be a massive help! Hope you enjoy this bit brought to you by my free time and the corona virus.
