Low Poly Space Shuttle Lift Off

Okay so iam a huge space fan which let to this make. I remixed a shuttle stl i found online with the custom made smoke under the shuttle in low poly optic.

0.1mm layerhight
5% infill
supports where needed in contact with the printbed

I chose 5% infill because i wanted to light the smoke up with some LED´s. 0% infill is in my opinion not possible because of some parts lying in free space without contact to the boarders. Did not felt
