So i should wait for my 3D version instead of shaving my stock plate?
I would get the 3D printed one and leave the stock one alone in a safe place. Because the official adapter (when released eventually!) will probably cost like $70 or so, and you'll need an intact Osmo ring to mount it, I presume. I unscrewed mine and kept it somewhere and just use the black 3D printed one for now. Plus, you don't want to have the extra expense of having to buy another ring for the Osmo later down the line.
