This is printed in one piece with PLA.
To get it right printed I had to trick the Cura slicer.
Nozzle size is 0.5mm, but to get more width I set flow to 135%. As you can see, the result is a perfect hull :-)
Thank you wersy for the great design.
And now I try to print it in pet-g again :-)
Well done, with the unusual settings you got a great hull.
Now I'm going to be envious of your huge printer... ;-)
