Remix - Đầu phun rocket Frau im Mond

A remix in an attempt to make my rocket model more accurate as compared to the movie version (Frau Im Mond  "Woman in the Moon," Fritz Lang 1926). Included in the photos, for reference, are two screenshots from the movie and a third photo found on the Internet (I've lost the source, unfortunately).

Another maker (Jaidei) correctly noted that the nozzle design of my model for the rocket Friede from the movie Frau Im Mond did not match the model used in the movie and posted a remix :

After some discussion in the comments section of the above remix (worth reading, if the topic is of interest to you), I concluded that Jaidei was correct and that my original nozzle design needed revision. However, I think that Jadie's remix, although more accurate than my nozzle design, was also incorrect in one detail -   the bottom surface should be flush with the ends of the nozzles.

Assembly and Use

Note there are two nozzle prints - a Lower (first stage), and an Upper (second stage).

If you previously printed my rocket model with the old nozzle design, you will of course have to remove the old nozzles first; they should come out without much trouble (I suggest using forceps or needle nose pliers for removal).

The revised nozzles are a snap fit, and are keyed just like the old nozzles, so be sure to line up the keys before pushing them in firmly.
