Notes:
1. Some components of this rocket require adhesive bonding, so a certain level of manual dexterity is needed for assembly.
2. I initially attempted to print the fairing as a multi‑color, single‑piece component; however, this approach consumed significant amounts of printing material and time. As a result, I switched to using colored decals instead.

The Long March 5B (English: Long March 5B, also abbreviated as CZ-5B) launch vehicle is a new-generation launch system specifically developed for the construction of China’s space station under the country’s human spaceflight program. Built upon the Long March 5 rocket with substantial modifications, it represents China’s most powerful next‑generation launch vehicle for low Earth orbit missions. The rocket has a total length of 53.7 meters, a liftoff mass of 837.5 tons, and a low Earth orbit payload capacity exceeding 22 metric tons.
