Finally got time to print this on my Ender3. Spent about 10 minutes re-orienting the smoke in Cura to fit the Ender3 build plate. Also tried printing the smoke a couple of different ways. Finally settled on .2 layer height and 20% infill. Used tree supports on anything over 70degrees because I'm running the HeroMe part cooler. Printed the smoke out if Amazon basics white PLA and the rocket out of 3d solutec PLA and the flame out of Hatchbox true orange PLA. Smoke took around 28hours to print, rocket and accessories took around 12 hours or so. Great design!
