Logitech x530 mount for racing seat RaceRoom 3055

I wanted to mount my Logitech x530 into my RaceRoom RR3055 rig.
 

The front left and right, I used off-the-shelf articulated speaker mounts attached to the triple monitor stand (8040 aluminum extrusion rig).

The center one uses the monitor attachment point, just replacing the cap and secured with the existing bolt.
For the rear ones, I took inspiration from an existing design by NawafH. With the same attachment idea, I adapted the speaker mount point specifically for the Logitech x530 satellites.

The rears are pointing outwards, not toward the ears. I think it may give a better spatialisation and also simplified the design.

I have also included the FreeCAD project file so you can adapt to your own seat or for different speakers.
