SpaceX rockets
I´ve also modeled the SpaceX ITS (announced in September 2016) and the SpaceX BFR (announced to replace the ITS in September 2017)
Falcon 9 and Falcon Heavy rockets. These will not print successfully at a small scale. This contains almost all outer detail, including grind fins, landing legs, both stages designed separately, a total of ten Merlin Engines in the Falcon-9 (nine in the first stage, one in the second), and a total of 28 Merlin Engines in the Falcon Heavy (nine in the first stage, one in the second, and nine in each booster rocket)
