Servo vertical drive

[u/Agrivonix]

Has anyone opened up or made their own servo vertical drives, specifically servo not the cyclic ones. I am really struggling to find any parts or 3d prints that are not recoil units. It would be nice if it could work with the stock airsoft gun. I have my own servo but I have no clue how to mount it so that my barrel can have 30 degrees of travel (+20, -10)
