Quest Pro rear pad replacement brackets, just the brackets. Slight modification of an original design by @Jorg_1321 (version A).

My Quest Pro rear pad brackets have fully broken off within 6 months of use, twice. This time I shaved off the broken parts and attached these 3d printed brackets to the rear strap with velcro.

Tested only on the KKCOBVR rear pad. The brackets actually feel a bit small and don't snap in too snugly, so I might edit the brackets here to be a bit larger later.
