I expanded on the Mesoamerican-themed bits range I've been working on.
There are vairants for each of the pauldrons; one plain, one Aquila, one Rainbow Warrior, one Blood Jaguar.
There are also 4 versions of Deathwatch pauldrons, and one with a sculpted Aquila.
The STL files for all these will soon be available from my Gumroad shop here:
