I couldn't find a proper file for this mount, so I created it myself. It uses a 25° incline which is probably a good compromise. On my test flights I did not see the props or any other drone part in the video, as well as I don't see the camera in my FPV feed.
Be aware that this mount is for the V3 Version of the Source ONE.
I printed it with generic TPU. Turn on the “avoid crossing perimeters” setting for best results.
