Also works for the original DJI FPV System camera using the standard 2 mounting holes on each side. Front holes are for mounting O3 Cam, they'll push it all the way to the front, almost touching the titanium cage but getting 99.99% of it out of camera view. You might still see a few pixels of it on the very corners.
There are 2 versions of cam savers, if you got your frame within the last year or two you likely have new ones. See the second photo for reference.
Attached are print files for Prusa MINI using SainSmart TPU.
