space shuttle model flames

This is my first ever design. I used Matter control, extremely easy.

I started from the design https://www.thingiverse.com/thing:2956434 and changed it to fit my space shuttle nozzles model. Thanks a lot to the original designer.

After printing I realised I made a mistake with the diameter of the smoke coming from the nozzle that serves as support. It is smaller than it should be.
