This is a bunch of pieces that make up a vaporator. I would suggest using a 10 line brim or skirt when printing out all the bits at once. The original parts came from Game Terrain Engineering, but I spruced them up with more technical looking parts. Other users on the FFG Legion forum have been contributing as well. You may need to file and cut some of the pieces depending on how well your skirt stays on. Use the long pole first for the main pieces and the shorter one after and twist the fins after gluing them on.
