Another couple of evenings playing with 3D Builder have left me with this, a US Navy PC-461 class sub chaser which will work out at a shade under 90mm long in 1/600. 3D Builder is a pretty simple tool to use but with some thought it can turn out perfectly acceptable models. I still need to work on getting up to speed with a more capable package, but for now this seems fine. Alas I can't print this until Monday to see if it actually works :)
