Happy to watch your progress on this! Remember it's not just the carbon fiber itself. The tube is the stiffest shape for the weight. Round tubes also have the benefit of being aerodynamic from every direction, but I imagine you could add a point on the underside to be more of airfoil shape... Connect the two following letters to see what I'm talking about: O V It would also stiffen it up more on the vertical axis. If you need more stiffness from there, you could make it wider at the root like a tree branch. Food for thought!
Could you design small holes for rod inserts to help with the stiffness instead of designing a lattice on the bottom? Could possibly insert stiff steel rods? Dunno how that'd go for weight, though
Definitely could, but I wanted something I could just hit print on as a first design to see how far I can go! Another idea was to just use carbon fiber rods and then 3D print the motor and body mounts for either end of it, so it's still something that can be recreated easily.

Good timing was thinking about printing drone parts yesterday 😂
Why didn't you try carbon fiber reinforced nylon, PA6-CF? It's stronger and lighter than PA6-GF.

Interested in getting this model to test it myself, any way you can upload the arm to thingieverse?
