Any chance to make it out of pre-core materials?
Also would be nice a list of resources for it.

Ohhhhh, me too! I dream to build my own rebel fleet. But it does not look sooooo simple and will need some help. A platform for the engines, I've already found. Hmmmm ......... If I just think about it, I need only one thing: platform, endurance and .... hope that the pirates do not catch me. In this sense: may the Force be with you .... and maybe you will see yourself in outer space

Star wars it's also my own design counldnt find a good ship for it that wasn't to small so made my own design

When you say galactic republic... which universe are you referencing? Your own? Star Wars? What? Pretty design,btw.
