The boat is constructed mainly of plywood and obeche but there will be a number of 3D printed items as well. I up-sized the plywood by one thickness from the original plan to correspond to the upscaling, but in hindsight, I could have stayed with the original thickness for skins and decks. Plywood for the bulkheads and keel (5mm exterior grade) came from Wickes whilst the skins and obeche came from Slec.
