ULA Delta IV Heavy Rocket

thingiverse

The original STL files for this rocket can be found on the web at http://www.ulalaunch.com/3d.aspx. This is a remix of the ULA Delta IV Heavy model, modified to make it easier to print large sizes. I removed the base and broke the model into three parts for faster printing and reduced material usage. To print this rocket correctly, make sure the bottom segment is printed upside down with nozzles pointing upwards. The connector pegs fit tightly, so apply petroleum jelly or reduce their size by a fraction to ensure they fit properly. Here's an insider tip: use the hollowed-out side boosters as secret hiding spots. **Print Settings** * Printer Brand: MakerGear * Printer Model: M2 * Rafts: Not necessary * Supports: No * Resolution: 0.2mm (default for high quality) * Infill: 30% Note that the goldish model was printed at medium quality settings and didn't turn out as well as the red model, which was printed at high quality settings.
