Lucky for you, my current build actually incorporates a section of wall with machicolations!
(You can see the sky through it because only the front wall is done)
Here it is from inside.
It’s not quite detailed enough to really be accurate to real machicolations which look more like this (below), but I didn’t feel like I could do a castle build without machicolations in some form.
Full build will probably be posted in the next few weeks, depending on how much motivation I have to finish it.
