This mount suits the CM275t all in one FPV camera and transmitter on copters with a 16mm electronics stack at 45°. The camera lens is centred on the craft so weight is shifted slightly off centre. The camera has 10 degrees of tilt which I find is fine for a small 1S build flown indoors.
The copter seen in the photos is a PepperF1SH inspired build using the TinyFISH FC and a ESC/Frame combo of my own design details of which can be found on my blog.
Wall thicknesses are designed for a 0.5mm extrusion width.
After printing drill the mounting holes to 1.5mm and then tap with an M2 thread.
A small dab of hot glue in the bottom of the mount will keep the camera locked in place.
