I wanted to print this all at once on the Replicator + and it turned out good, but the fins were too thin at it's current size. I just brought it into TinkerCAD and merged the two pieces, then used the NACA part to build some beefier fins. I also added some mass to the exhaust vents. When I finally printed it I set it at 115% to make everything a bit larger. Lastly it has Mesh Mixer supports in an effort to be frugal. https://www.instagram.com/p/BjaA4I3g0Uc/?taken-by=hlmodtech
