Here are two maps I made for the DnD 5 Starter Set: The Lost Mine of Phandelver. Of course, they can be used for whatever you like

First is Cragmaw Hideout:


And then we have Cragmaw Castle:


I'm not too happy with some of the details of the castle, but after working quite a few hours on it, I kinda wanted to finish it. Some of the rooms could also use a bit more stuff in them, but it's easy enough to add something when I know what I want. Btw. the holes in the wall are narrow arrow slits, so archers can fire at invaders from inside. The layout of the castle makes pretty much no sense in my opinion, but I still kept it to the original in the book.
