A full detail model of the Ariane 6 rocket currently in development with Arianespace and ESA, the european space agency. The model contains an STL of the full rocket, STL's of the fairing, the separate stages, the boosters and the core with preattached boosters as well as a very simple stand to keep the model upright. All models are scaled to 1:1 full scale, so you have to scale it dow nbut all thin walls and details have been thickened to be printable even in a relatively small rocket. While the rocket is still in development the model contains all currently known details visible from the outside and is precisely dimensioned to the current state of the concept.
The Ariane 6 is a successor to the Ariane 5 rocket, being slightly modernized with a different production infrastructure and more smaller boosters as well as modernized engines. One of it's main features is the variability of being able to fly it with 2 boosters or 4 boosters thus allowing to launch relatively small payloads without wasting too much performance needlessly. The fairing is large enough to launch several payloads at once though and the rocket is capable of inserting payloads directly into geostationary orbit with a relightable upperstage.
