Betafpv v2 case Camera Butter mount

thingiverse

Remix of https://www.thingiverse.com/thing:4597891 (Mount should also work with Telerin ND filter) I wanted an ND filter mount to fit over my Betafpv NakedGopro v2 case and have a Camera Butter ND filter stick on the flat surface. But all the ones I've tried, when the mount is secured over the case, it warps. So the Camera Butter doesn't stick flat on it. This one I found doesn't warp but I had to make some changes to it so that: 1) The flat side where Camera butter would stick on is as flat as possible when mount is on the betafpv case 2) The filter is moved away from the GoPro lens (I have scuffed a lens using other mounts with ND filter...) 3) Camber or bevel the lens opening so that there are no black corners of the mount in the GoPro recorded footage.
