About this model

NEW! as of June 17. This is now a complete modular rocket system! Pick a nosecone, body tube(s), fincan, nosecone coupler, and voila! A semi custom printable rocket! I plan to be adding new sections on a regular basis so check back often! Feel free to leave feedback if there is some feature you'd like to see that isn't up yet :) Important dimensions to make compatible modules: Tube Outside Diameter - 1.75in Tube Inside Diameter - 1.667in Coupler Tube Outside Diameter (tight): 1.663in Coupler Tube Outside diameter (looser): 1.659in NOTE: The designs are closely based on the Legacy design and should work well, but many of them are still untested. I'm working on it, though.
