F450 Yi 4k Gimbal sg90

I use this with my yi 4k lite camera and it works great.
Attach "attachtocamera.stl" and a servo arm to the camera cover, then insert a paperclip inside "attachtocamera.stl", attach the servo arm to the servo with some glue and enjoy!
I printed this servo arm https://www.thingiverse.com/thing:348754 and then I cut off the excess.
Happy printing and flying!
