A Guns of Icarus Online Ship I made when I was bored, it is a player-sized model, and is a very miniature version of one of the Airships from the game. It has no features, besides looking pretty, it is able to be duped and no zone-bricks were required for the finale version. I'd expect this to be used in a Mini Empires RP or something, but I'm not releasing for download unless people REALLY want it.
Here it is below next to me:

I can't find any image of the original spire that is big enough to be visible and high quality, so you are going to have to look it up yourself to see the similarities and/or differences.
Keep in mind that I was building this from memory, so it isn't 100% accurate.
