F1 Engine with only 3 parts to print

thingiverse

In the spirit of the one-part J1 engine for this model here: https://www.thingiverse.com/thing:3213435, I decided to tackle the 30+ parts of the F1 engine. If you struggle with gluing PLA in a permanent and "structural" way, or if you can print dissolving support or are really good at pulling off tiny threads, this will save you a ton of time and effort with your Saturn V model. I also noticed that the original F1 Engine is missing the "gimble" supports that attach the engines to the bottom of the rocket. I modeled those in Solid Works 2017 and added them to the Engine bottom STL file. These are designed to easily produce five engines, all exactly the same height, and could actually hold up the rocket with only three dots of super glue per engine. Print the "bottom" with the Engine Bell facing UP with supports at 80 degrees... (more if your printer and/or filament demands it). Print the top with the fuel pipes DOWN with supports at 60 degrees. And print the Tank Coupler with the "pin" up... Take your time to trim the supports... (the engine exhaust pipe is very fragile... as are the fuel pipes)... Glue to the bottom of the rocket at each gimble support and the top of the engine bell, and you're good to go.
