This is a 3d printed rocket gimble that is scaled for 9 gram servos. However you can beef the size up by 150 % to get bigger rocket motors inside the housing--The same goes for the servos. Keep in mind once you surpass F class rocket motors you'll need certifications. In the photos of my version I blew it up quite a bit. I built mine out of 50% carbon fiber/PLA for the motor housing. I used regular grey PLA for the rest of the frame.
I hope you like my stuff.
