My players in Tomb of Annihilation obtained use of a Sailing Ship, so obviously I had no choice but to design and print one up that had the same floor plan as the sample map in the 5e DMG.
The helm and capstan rotate. The berthing compartment door opens/closes. And the ballistae pivot in all directions.
*The Capstan and helm were remixed from Jabberwock's Sailing Ship
**The Ballistae were remixed from MZ4250's Dwarf Rogue Crossbow found in his Rogue and Ranger collection.
***Edit - Added split main deck and cargo hold files for smaller print beds.
The lower decks were printed at 0.2 resolution at 40 mm/sec.
The upper decks were printed at 0.15 resolution at 25 mm/sec with supports and support interface due to the delicate nature of the railing.
Some of the connections need to be sanded to fit together properly. The upper deck connections need to be tight.
