TARDIS

OK, it is just about possible.

This one took five and a half hours, and went slightly wrong after around five hours so a slightly off effect near the top.

But printing for that long means I have managed to solve most of the problems I think.

I'll try again when I get blue plastic.

Obviously this is a scale model - well the outside is to scale, if I tried to do the in-fill to scale I would need a lot more plastic :-)
