RunCam_Thumb_Mount_remix

Remix - Scaled down the base fitment and added a longer slot to allow more interoperability on different sized frames. Added a cut out to stop the mount switching the camera off. Fitment is tight, but loosens up over time. Betaflight 1s batteries work well, can also squeeze in most other 1s batteries.
NB - slide in the camera, attach a power pigtail once it's in place, then sliden in a battery and plug in the cable. If you try and slide the camera in with a power cable attached you'll just rip it off.
