wow , a model to print , thanks you to have do that in cad , i dont know how i can do something like that i have try , but , need more time to be able to understand how i can . the number of kg to do that is not important , for poeple they search for a good model , , but just a model to be able to print to do something like that with fiberglass , too , the infil need to be hi , to have strengh , and all small compartment need to be watertight , 1.6mm thick , i can try , the dimensions , are not write , i need big printer or not , if that work , i come back to tip the model .

I've now calculated probable plastic use for one of these using Slic3r gcode generation, and with 0.4mm nozzle, 0.3mm layer height, 1 perimeter, 2 solid layers, and a mere 2.5% rectilinear infill, one of these midsections would take 13.2m of 3mm filament to print. That adds up to about 3kg of PLA for a single 7ft hull, which is pretty expensive at current prices.

Therefore I'm going to put together a design using a cheaper construction method with similar sections; thin strip-planking over printed, milled or laser-cut bulkheads.
