I made a Cave Bear mini for Gloomhaven! In order to get it to print successfully, I split the head off of the body and printed it at a different angle (as seen in the posted screenshots from Meshmixer). I made the trapezoidal key (for guiding the head onto the body) a completely separate piece with about a .02 mm tolerance; if you need more than that, just print it a bit smaller until it fits nicely into the holes. I made this with a .25 mm nozzle and printed it at .05 mm layers; I'm not sure how the smaller details like the claws and teeth will turn on with larger settings.
