This is a backpack (and mount) for a FPV setup. We created it to perfectly fit the FatShark 600TVL/700TVL style cameras and the FOXEER fpv video transmitter. (https://www.youtube.com/watch?v=eQiH3tQ7lak)
Print off many of the Cradles bases and hot glue them to your models and you can pop the FPV backpack on the one you're flying.
UPDATE: New versions added after subscriber requests with 15 and 20 degree tilts..
I use a hairband for the elastic. Happy flying (and printing)
