I have 3D printed a good majority of the parts, have gone back and tweaked them, and reprinted more. I've started assembly as well, and am aiming for a flight test the first week of May, sans the outer shell. I've uploaded the files as they are now, however I would discourage you from printing them, as almost any are subject to change prior to the test flight. Feel free to dig around and make suggestions however :)

Below are pictures of both the partially assembled NAVI MK1, as well as the CAD renders as they currently sit.
