This is my model of the entire Launch Tower with the Superheavy Starship from SpaceX. The entire build is roughly in 1/144 scale and has several functions.
Both arms are movable and can slide on the tower as needed. They also come with a safety pins to hold the Starship securely in place.
The Hotstage ring is very much redesigned be my to follow its function even in this scale and with being 3D printed but it indeed holds the 2 stages together and by removing it, you can detach the Starship from the Booster.
The whole build is divided into its own individual folders and includes all the model plus a “whole” model for each stage so that you can see how will it look when assembled.
Because it is rather complex build, I recommend to watch the assembly video.
The author marked this model as their own original creation.
