Fan art of an Astral Dreadnought for 28mm tabletop gaming, scaled to be a gargantuan creature in d&d terms, would also make a good demon lord.
Note that this model is very large, once completed and assembled it is 16cm tall and just over 25cm long and weighs a little over 400 grams.
Of course that does make it rather intimidating for your players...
My example mini was printed in parts on a stock ender 3 with PLA+ at a 0.16mm layer height and painted with games workshop paints.
I wouldn't suggest printing it in one part, though I've included the files in case someone wants to scale the mini down to a smaller creature size.
