The files here represent a 1:72 scale model of a Viking 32-seater with 16 oars on each side. This ship would have been slightly more than 24 m in length, and as I mentioned elsewhere, such a hull cannot be printed out even diagonally on a reasonably large 3D printing plate (i.e. 22x22cm). The only way is in two pieces. Or in reduced scale, 1:100 or 1:144.
This model is the type of 32-seater that was found at Gokstad or at Oseberg. These ships were about 5 m wide and dated to ca. 850-900 AD. These finds established what most of us think of as a Viking ship today. It is easy to imagine such a one coming back from England with a fair amount of loot, both under the removable deck planks, as well as heaped around the mast in the middle. Maybe you can even try to set up a tent in the middle. I advise against displaying the ship with a full crew at the oars, plus all their shields hanging down the sides, plus the ship under full sail all at the same time. Just saying, because this is how they are shown in many romantic paintings where the crew also had horns sticking off their helmets…
The rudder here also has become larger and more intricate compared to the small warship in the other post.
Update 14.06.2020: to allow printing out on a FDM printer at very small scales, I added here a version with extra-thick hull elements. This "Small Scale" version should now give reasonable results when printing out at down to 24% size (0.025mm nozzle, 0.06mm layers, PLA) with both hull versions. For convenience, the Small Scale model is available as a single joined-up hull, with rudder and benches already added, and sized at 50% of the other files, i.e. at 1:144 scale. With these ships, your 15mm, 8mm or 6mm armies should be all set now ! Happy Gaming !
Update 10.08.2021: The 32-seater hull has now been overhauled to eliminate some of its previous slightly angular look. Stay posted as these crew are getting an overhaul and new colleagues join them !
Update 30.08.2021: Leveled out the profile of the keels in the two halves of the hull (parts A and B). Also the keels at both ends of the ship are now more sharply rounded which makes the model more historically correct.
Update 21.02.2022: Have nopw added waterline versions for both hull halves on request from some of the users here.
