"But the Targaryens managed to raise a castle here. Simpletons claim they used ancient Valyrian sorcery, forgetting that the Targaryens brought a small army with them from Essos; there's no magic in strong backs. Though admittedly the castle is unlike any in Westeros, foreign and... strange." ―Stannis Baratheon
Dragonstone as seen in Game of Thrones. I based this on one of the concept arts and imagined the rest, made it look a bit like a dragon from above too.
I've made this printable from parts to assemble larger models or just to print with different filaments. All the parts should fit as they are but can be pretty tight, attaching the water is a bit tricky but it does work well when done right and it stays together without glue.
I printed a smaller one with a resin printer too, which I then painted. The big print has zero post processing done.
