This is a remix for the center part of this TinTin rocket model: https://www.printables.com/model/204744-fusee-de-tintin-rocket-tintin
I found that the center part for this model is not finished. A thread on top and bottom is needed to avoid to use glue to join all the parts.
I've added a thread on top and bottom and now the rocket can be mounted without using glue.
Supports are needed for the bottom part.
EDIT: Thanks to @Alpes86 for it's feedback, the model is updated to a correct one with no hole issues on the thread.
The author remixed this model.
Add thread to avoid glue
