A design of a spacex rocketship. About 6 inch tall. No need for supports. Printed at 0.15mm at 15% infill. This was going in a car so it was printed with PETG.
For the plume, supports are needed, and depending on your adhesion, a few rafts would not hurt
Once printed glue together and add the plume.
