My CineBee 75 HD video stream suffered from lots of jello, so I experimented to get rid of it and found a solution consisting of these steps:
Make more room for the camera to swing horizontally by filing some material from the front ducts, see photo.
Replace the factory camera mounts by optimised mounts printed with TPU for giving the camera the frreedom to swing in any direction for compensating vibration.
Ensure the camera does not touch the frame and can swing freely.
In addition to the STL file I have added the FreeCad source, too.
Please also read my notes on printing below.
