3rd-Rate Ship of the Line

The model is a two‑part assembly: a hull and a deck.

The hull is designed to be printed upright and requires supports. Internal shelves are built into the structure; these hold the deck once inserted.

The deck is a separate piece, intended to be printed on its side, also with supports. It slots cleanly into the hull and rests on the "shelves". 

No supports needed for the stand.
