My 3d printable rendition of the CSS Hunley, this model has not been printed yet but it has been sliced and I have checked it- this doesn't mean they are perfect, but they should be fine and they are printable. It has several ways you can print the bow as well as hollowed out parts for resin printing. you will probably need to support the spar with ropes(like it was on the real thing). Also I will change this when it is printed- should be soon I just haven't done it yet.

Also if you like models like this, I do have a pateron with more like this(though I'm just getting started so its not very full yet).
