I recently purchased (with a partner) a Monoprice Delta Pro 3D printer. While I'm training myself how to use freecad to create 100% my own component design parts I have been downloading objects from thingiverse and modifying them using Tinkercad. That involves so far mainly scaling up or down components I want to use on my models. I doubt that I will ever get to the point where I will draft and print out all the components to build a sailing ship frame by frame. For one thing I don't think I have enough time left to complete such a task. So I will remain content to create add-ons to kits I am building to improve the overall look. So far I have downloaded several Civil War Ironclads that are in thingiverse and have plotted out 2 of them. The USS Monitor and the CSS Virginia at the scale of 1:250. It will take a lot of additional parts and work to get them to an acceptable level of detail. One piece of reference material I have is the 1:250 scale card model of the CSS Virginia from the Paper Shipwright. I don't anticipate reaching anywhere near the level of detail seen on the Ironclads from Cottage Industries models as they are 1:96 scale.
