PUDA Stingy frame is designed for a full size FPV camera and I got a Caddx Micro F2.
I didn't find any adaptor with the hole at the back to secure the angle, so I made this one.
M2 screws work well with the PLA without nuts on the inside.
I think (not measured) that between 35/40º is the max angle for the camera.
30 (but doesn't matter much)
Used 5 for top, bottom and perimeter layers. Solid as a rock and the screws hold pretty nicely.
