For an upcoming Epic-Scale game of X-wing, I build a Special Missionobjective: A small Stardestroyer.
I found a good template for printing here: http://www7a.biglobe.ne.jp/~sf-papercraft/sf/destroyer.html
I scaled it up, printed it and glued everthing on foamcore.
It is still a small Stardestroyer, but big enough to make an Impact.
It is not painted yet but I think it is already quite impressive.
