World of Warcraft style shoulder pads . by printing 3 or 4 sets at different sizes and fixing them together it should make a good shoulder pad based on World of Warcraft.
I have invented a new set with holes and a linking system to put them together
check out my shoulder armour set 2 and my modular armour system
print as shown and the spikes do not need supports and look better for it
only the underneath needs supports `you will also need a brim or raft
