Here are some masts I made for the Assassins creed ship of the line model. Nothing fancy, and didn't go for accuracy of the pictures, just wanted something to flush out the model for a maritime themed DND session. For some reason it isn't letting me link to the original file, but I remixed from https://www.thingiverse.com/thing:5984049 and used them with the same models, just scaling to fit the different sizes as desired.
