Thanks for the replies so far, I am glad you people like the tugs. But this only my first try, we will first have to see if everything fits together as I had planned in my idea. Having an idea, making the design drawing is a rather small step, but to design a 3d model out of a drawing is a larger one..
Yes I do sleep, itīs most of the time, just before going to sleep the ideas pop into my head..
Alltough I must say, research, like collecting photographs and pictures for these models allready started while still building the Titanic.. in November 2010.
The design, printing and testbuilding were indeed started the last couple of days after finishing the Titanic.
