TBS Caipirinha Yi Action Cam Mount with USB access

Added a hole in the back for charging during flight. Just power it with 5V on the USB port and the weak YI battery will no longer drain.

Here's a video on how to make an on-board charging cable:

EDIT:
Added a version with an open gap on the backside. This way it's easier to withdraw the camera with the cable plugged-in.
