This is exactly how I did it. I built a 10" quad fully 3d printed.
I can personally recommend carbon fibre frames for their stiffness, weight and durability. And then print the add-ons like camera mounts etc.
I had great fun designing and printing frames, but they just weren’t robust enough and it became a pita reprinting after every crash.
