If you’re looking for some bighats, you can’t go wrong with our very own @Brawniac 's STLs here.
For some 80s-esque goodness, there is CP Models chaos dwarfs range here.
For some more Legion of Azgorh vibe, there is that popular patreon that I can’t remember the name of for some reason.
These of course aren’t even the tip of the ice berg, there are so astonishingly many great chorf minis out there you’ll get lost at sea.
